The Nature of Demons is a dark, immersive journey into a post-apocalyptic world that feels both brutal and unexpectedly tender. The story follows Jacob Freeman—a husband, father, and lawyer—whose life is ripped apart by a demonic transformation and the collapse of the world around him. What makes this stand out isn’t just the gore or chaos, but how human it remains at its core.

The author paints vivid, cinematic scenes filled with horror and suspense. I appreciated how Jacob, even twisted by something monstrous, still fights to stay grounded in love and protect the people he cares about. The character work is strong—especially in the dynamic between Jacob and his daughter, Micah. I also loved the quotes from Micah at the end of each chapter; they add a hopeful, grounding presence amidst the darkness.

It’s not a light read—there are graphic scenes, strong language, and mature content. But if you’re a fan of dark speculative fiction or mythos-driven horror, this one’s worth picking up. A strong, emotional, and well-written story that leaves an impression.

First off I want to say I couldn’t put this book down the moment I picked it up. I was heavily invested in Jacob, Rebecca, and their daughter Micah fight for survival in post apocalyptic messed up world.

Jacob was a character I didn’t know either to like or dislike at times but a man who would do anything to protect his family is a winner in my book despite the obvious flaws he has. Rebecca might get some hate I imagine for lots of reasons but I really couldn’t find myself disliking her. She was in my opinion the only voice of sanity despite her own not so wise choices. I am really hoping for some sort of character growth with her pleeeease. Micah was a ball of sunshine and not one flaw with her. I’m looking forward to what she brings to the story. As for another character (I will not name) I’m not sure I quite like them yet. Though not a bad character in writing I just have to quote Jacob “The Freeman family plus one”

As for characters who came through the story I was interested in them all. Despite the horror happening in this story I liked the of tender but bittersweet moment that happened early on. As for the others I’m really looking forward to what J.D. Carmicle will introduce. I enjoyed his writing style very much and the world he created it held me in a tight grip in which I finished in 3 days

So thank you NetGalley and Demon Mythos for allowing me the opportunity to read this free digital copy for my honest review. I will be looking forward to what J.D. Carmicle writes next!

I really enjoyed this book, the atmosphere, the world building, it was a good book, I highly recommend reading this. It was different and really interesting.

Supernatural meets The Walking Dead in The Nature of Demons. A supernatural-apocalyptic horror that packs a punch from the very first chapter.

What starts as a normal day for Jacob, Rebecca and their daughter Micah turns to utter pandemonium as it also seemingly does for the rest of the world. Homes and vehicles are abandoned, and corpses decompose in the street, strewn around the town like twisted art installations.

When night falls and demons come out to play, how far will Jacob go to protect his family - from others and himself?

Action-packed, eerie and gruesome from the get go, this had me on tenterhooks throughout. Both well written and well and truly unnerving. Thank you to the author, publisher and NetGalley for sharing an advance copy!

I heavily appreciated the content warnings. This book has such a cool cover and the premise is spooky! This book has a different storytelling format than what I’m used to and my brain is simply not enjoying the way the story is being told. Those that enjoy a bit more of an artsy execution with storytelling in horror will love this. I am a picky reader and want to know what is happening in a clear format. This book has unique chapter formatting that I think will work really well in print and audio edition. It’s definitely very scary and disturbing.

Thank you for allowing me to sample this eARC! I appreciate the opportunity to leave honest feedback voluntarily,

Will they survive doomsday? What awaits Jacob in the post-apocalyptic world? Find out in this amazing book!

I thoroughly enjoyed the unique and descriptive nature of the author in crafting his storytelling. True to his preferred genre, the author’s narration is very picturesque and leaves very little to the imaginations of the readers. The author fills each chapter with suspense and incredible gory details meant to pluck at the reader’s emotional heartstrings. I hope the author becomes more adept at ensuring happy endings in his stories.

The character developments in this book are also very amazing. I loved the fact that Jacob remains human even after being demonically altered and almost kills Micah in a bit of a frenzy. In the post-apocalyptic world, he celebrates Halloween with her, takes her to the hospital, and soothes the more pessimistic Rebecca. He also befriends Judith and makes her protect his family.

The book is also very entertaining and filled with quotes from Micah at the end of each chapter. My favorite is, “Find good things in the world. Even if it looks like everything is as bad as it can be, there’s something good you can find.” A good and applicable morale, I must say.

This book is excellently and thoroughly edited, so I did not find any grammatical errors or typographical mistakes. As a lover of all things fictional, be it literary fiction, science fiction, or dark speculative fiction, I, Michael Lartey, find this book to be thoroughly appealing and fun to read. The author’s context and style in this book powerfully and incredibly convey emotional intensity; therefore, I rate it 5 out of 5 stars. This is one of the best books I have ever read. I absolutely recommend this book to lovers of fiction, mythos, and dark fantasy.

However, because this book contains profane words and mild sexual content, I recommend it only for adult readers.
