Expertly written and researched with complex and well developed characters, I thought No Safe Space was sensational.

This book was so well researched! I was fascinated by the police procedural details and the authors knowledge of OCD and mental heath conditions. It was so authentically written and these details and the understanding of mental health conditions made it such a powerful story.

I loved the main character Field. She is strong, wise and layered. I loved Callum and Lily’s relationship and thought they were perfectly flawed if that makes sense!

The story and characters were so well developed and I could really visualise the story, so much so it felt like watching a crime police drama like Happy Valley or Vera.

The ending made me actually sob, it was so powerful and moving and I did not figure out who the killer was!

Hannah Brennan is an exceptional writer and I cannot wait to read what she writes next!

No Safe Place is the first novel in the Detective Liz Field series. It’s a police procedural that grabbed my attention from the synopsis and didn’t let me down. A child psychologist is stabbed and left for dead then a young woman is stabbed in the middle of the night. The connection? She was his patient but that was years ago, so why are they being targeted now? Liz and her team must find the perpetrator before the case is given to another team and before there is a third victim. Well written, it will keep you guessing to the end. Thank you to NetGalley, Avon Books UK and the author for the chance to review.

Firstly a big thank you for the opportunity to read and review this fantastic debut .
This is set where I grew up and in my local areas now which always enhances the reading experience for me .
I loved this book and am glad the author already has book 2 lined up.
The protagonist is great and relatable as a working mum who’s very headstrong and determined !
The storyline is intriguing and captivating.
It’s a compelling and addictive read that will have you racing through it to discover the truth .
Packed with tension and an array of interesting characters this is a twisty read.

Just finished No Safe Place by Hannah Brennan and wow… this one pulled me in fast. It kicks off with a psychologist getting brutally attacked, and it turns out he used to run a study on five teens with OCD. Now, years later, those same kids are adults—and someone’s coming after them.

What I really liked was how the story is told from different people’s perspectives. Sometimes that can get confusing, but here it actually makes everything come together better. You get these little glimpses into each character’s head, and it keeps you guessing who’s hiding what. It also builds this slow, creeping tension where you’re not sure who you can trust—if anyone.

The main detective, DCI Liz Field, is dealing with her own baggage, and as the case goes on, you realize it’s hitting way too close to home for her. That added a whole extra layer to everything. It’s not just about solving the case—it’s about dealing with the stuff we try to bury and pretend isn’t there.

If you're into crime stories that are dark, a little emotional, and full of twists, definitely give this one a try. It's unsettling in the best way.

A solid debut from Hannah Brennan, an enjoyable read but not particularly gripping for me.
I found this quite a quick read, helped by short chapters with alternating points of view, and the start was strong enough to draw me in, but I think it needed a bit more depth. Field isn't a particularly likeable character, I'm not sure I'd want to read more in a series featuring her, and I would have liked more of a background into her son and their relationship.
I appreciate the authors idea to spread awareness and change public perception on OCD based her own experiences, and I did learn more about different manifestations of OCD from the other characters as they were given a little background.
There are a few twists and a couple of events to throw you off track, and I didn't see the reveal until it happened, but it didn't really offer anything different to any other police investigation story.

I LOVED this wonderful debut. Taut, tense and thrilling, NO SAFE PLACE draws you in with the wonderful procedural detail and stunning characters, and won't let you go until the twisty end.

We follow DCI Liz Field as she investigates a series of murders that seem linked to an old OCD clinical trial that involved five young teenagers. I love the way the author brings us unto the world, sitting in the humanity and the procedure of the police as they investigate which heightens the tension and the stakes of the story as it grounds itself in reality. I love, love, love the complex and grey relationship of Callum and Lily and I enjoyed learning about their own varied and different experiences with OCD. The authenticity of the depiction of OCD, brought on my the authors own lived experiences, really shone through, adding depth to the story and its characters.

I raced through this and I can't wait to read more in the series.

No Safe Place is an impressive and emotionally grounded debut that blends the tight pacing of a police procedural with the psychological complexity of a character-driven thriller. From the opening scene—a brutal stabbing on a quiet residential street—the novel wastes no time pulling the reader into a web of past trauma, buried secrets, and unresolved guilt.

At the heart of the investigation is DCI Liz Field, a refreshingly complex lead with a quietly compelling voice. Brennan does a wonderful job weaving Liz’s personal struggles into the narrative without ever letting them overwhelm the case at hand. We’re introduced to a group of former OCD trial participants, now adults, whose lives have been shaped—sometimes quietly, sometimes violently—by their teenage experiences in the study. When their former psychologist is found stabbed, and one by one the group seems to be targeted, the question quickly becomes not just who is responsible, but why now?

What stands out most is the sensitive and authentic portrayal of OCD. Brennan writes with both nuance and clarity—likely informed by her own lived experience—which brings much-needed depth and empathy to a subject often misrepresented in fiction. The characters are flawed, human, and deeply believable. I found myself especially drawn to Lily and Callum, whose relationship is layered with shared trauma and cautious hope.

The mystery unfolds through multiple perspectives, each contributing a new layer to the story without ever muddying the pace. There are enough red herrings to keep the reader guessing, but the final reveal feels earned, not gimmicky.

Tense, thoughtful, and refreshingly honest in its treatment of mental health, No Safe Place is more than just a solid thriller—it’s the beginning of what promises to be a brilliant series. I’ll definitely be following Detective Field’s next case.

Thank you to Avon Books UK and NetGalley for the ARC.

A psychological thriller that takes you into the past of the characters and strings you along to an unexpected ending. Fifteen years ago, five vulnerable teenagers took part in a blind study of OCD. Now, their psychologist has been brutally stabbed and left for dead. The police must determine whether the murder is related to the study and, if so, why the psychologist was targeted.

Book 1 in the new Detective Fields series.

The author writes with an understanding that can only come from a history of suffering from OCD herself. She bares herself and allows her flaws to be revealed as you get to know and understand each of the characters. Much respect for opening herself up to criticism through a work of fiction. I look forward to reading the next book in this series.

Thank you to Avon Books and NetGalley for allowing me to read the arc in exchange for an honest review.

I’m a big fan of police procedurals so I really liked getting to know Detective Field, we got to hear a bit about her back story in this alongside her son Toby, so I’m intrigued to see what comes next.

This thriller started with a bang with a body being found with multiple stab wounds on a residential street and from then on it kept the pace. The story was told from a few perspectives, alongside Field we also had Callum and Lily’s story which I found really interesting. The whole book shone a new insight to OCD and definitely taught me a few things!

There were a few twists and turns in this that kept you wondering who the killer could be, one minute you’d think one person and then a clue or fact would drop and you’d completely switch. Personally I didn’t guess the ending but thought it was really well written. I’ll be back for book 2 for sure!

Fifteen years ago, there were five teenagers, who took part in an OCD trial run by Dr David Moore. Fast forward to the present, David Moore has been found stabbed and DCI Liz Field is tasked with investigating this crime and then another body, a former patient, is discovered with stab wounds. How are they connected? Who is behind the crime? Why is it happening now? DCI Fields and her team have to protect the other former patients along with uncovering the truth behind the murders. It was well written and I loved how the characters interacted with each other.

⭐️⭐️⭐️⭐️💫 (4.5 stars)

No Safe Place is a tense, twisty psychological thriller that hooked me from page one. Fifteen years after a groundbreaking OCD study, the psychologist behind it is brutally attacked, and the former teen patients may hold the key to what really happened.

Hannah Brennan masterfully blends a chilling police investigation with rich psychological insight. DCI Liz Field is a compelling lead, and the shifting perspectives kept me guessing until the very end. The pacing dips slightly in the middle, but the final reveal is worth it.

Smart, suspenseful, and deeply human - this is a must-read for thriller fans.

Thanks to the publisher and NetGalley for the ARC in exchange for an honest review.

A well crafted procedural that hangs on the murder first of David Moore, a psychologist and then of one of his patients in vicious attacks. DCI Liz Fields, who has just about had it with police politics, has the case. Five teens were in the study of OCD fifteen years ago, What happened then that turned one of them (or is it one of them ) into a killer all this time later? And who? And why now? Liz has many questions and struggles a bit to get the answers. This is an interesting look at group dynamics as well as informative about OCD. The characters are good, the plot keeps you turning the pages. Thanks to Netgalley for he ARC. A good read.

This was a great debut novel and the start to what I hope will be a new series featuring DCI Field, who I thoroughly enjoyed as main protagonist.

Centred around a group of young people and the doctor who treated them some years ago in a mental health facility, one by one they appear to be targeted by an unknown assailant. The group suffer from various forms of OCD, all of these brilliantly described by the author, which made the reader better understand their thoughts and actions.

The plot was well written and the characters in both the police setting and in the various lives of the OCD group participants were easy to warm to and feel empathy towards.

I look forward to reading the next in the series.

Thanks to Netgalley, the author and the publisher for the opportunity to read this book in exchange for an honest review.

This is the author’s first book and they are off to a good start! A fun read I flew through. I think it has the makings of a good series!

Thank you Avon Books and NetGalley for this Arc copy of No Safe Place

The story is a multi POV thriller with police procedural elements following the deaths of people connected to a psychological study on OCD patients. It starts with the death of the psychologist who wrote the study and we see the story unfold from many characters perspectives. This book beautifully details various sorts of OCD and how some of the characters were and are affected by it. The twists and turns leave you thinking you know the killer but then switching things around again and again.

It is a thoughtful well written thriller that explores perhaps a lesser known facet of mental health as well as the sometimes troubling interpersonal relationships of sufferers and their loved ones.

I thoroughly enjoyed getting the opportunity to read this and welcome it's unique perspective within the thriller genre

The attempted murder of a brilliant clinical psychologist opens this thriller that tracks the meticulous efforts of DCI Lucy Field over the course of the investigation and also explores the turbulent relationship between two of the doctor’s former teenage patients, Lily Stewart and Callum Mulligan.

When DCI Field snaps at her subordinate Riley for his mishandling of Callum, an agoraphobic who turned his teenage OCD into a best-selling book, she has our sympathy as its revealed her son battled mental health issues.

Three days and three stabbings later, the connection between the good doctor and his former patients is clear based on clues left at the scene of the crimes. But who is targeting them and why?

The writing at the sentence level is simple, clear, evocative. Field’s exhaustion and frustration. Lily’s gut churning intuition. Callum’s masked indifference. It all sets a tone that mental health recovery and the people it affects is an ongoing battle.

Would I have ever guessed the perpetrator? Not at all. And that’s what I liked. For the perp, what a surprise the truth turned to to be.

Thank you to #NetGalley, the publisher #HarperCollins, and the author #HannahBrennan for the ARC of #NoSafePlace. Go read it!

I really enjoyed this book. I was gripped from the first chapter and found it difficult to put down. There were so many strong characters that added so much to the storyline with their various relationships, and the clever way they were developed . OCD was a brave topic to base the main content, but I found it very informative and interesting. I am really excited that the next book in the series is already written, and I can’t wait to read it.

A smart, emotional debut with a great lead and a refreshingly honest look at OCD issues and mental health. While I wished for a slightly deeper ending twist, the writing, pacing, and procedural depth make this a promising start to a new series. It’s great to see more thrillers tackling these themes with care. 3.75 stars!

Detective Field is called to a scene where a man who has several stab wounds. The man was successfully taken to hospital but later died from his wounds. The man had a ripped page from a document that had details of a medial trial which involved OCD patients several years ago. The man who was named David now a lecturer oversaw the trial. When a woman is also discovered dead, they discover that she was one of the patients on that trial and the others Lily and Calum that don’t live that far away was also on that trial. Can Detective Field find the murderer before it’s too late and another body turns up.
No safe place is the debut novel by Hannah Brennan and the first in the Detective Liz field series and I can say this is a compelling read. This has a good storyline and great characters especially detective Field.
The storyline was also a learning experience for me when I read about the different types of OCD as I wasn’t aware of them. I only thought there was one type.
I can’t wait to see how this author develops and the next book in this series. 4 stars from me.

A good debut! I don’t generally love procedurals and especially dislike the usual endless blathering about the exceptional character of the police protagonist. But the author was excellent at depicting the realities of OCD, as a person affected by it herself, the characterization of the protagonist was in-keeping with the themes of the novel, and I liked the somewhat left-field ending. 3.5 stars (rounded up to 4)/5.

Thanks to NetGalley and Avon Book UK for letting me read an ARC.
