Superficially this is a decent holiday read, it bounds along and keeps you guessing, like a speed game of chess on a moving train.

But I hated the preachiness of the eco warrior tribe, and felt the very Americanised slant left me wanting to get my red pen out and add corrections throughout!

I have no doubt this book will leave most very satisfied with a good tale and fast pace, but I really wished for a more polished and measured tome. Shame.

This was a good read - fast paced, tightly plotted, quirky characters. The writing felt a little stilted in places and you can tell from the blurb that it won't be high literature but none of this is enough to detract from the overall solid performance. Recommended.

My thanks to NetGalley and publisher Penguin UK - Michael Joseph for the e-copy.
I really enjoyed this book. It's well-written, has believable main characters and excellent dialogue. The story is that of an eco-terrorist the authorities have named the Green Man; he's a bomber and the destruction of each of his targets publicly underlines different aspects of their contribution to global warming and Earth's demise. He always claims responsibility for the attacks and gives his reasons in the form of hand-typed letters posted to news outlets. He has a national following among environmentalists.

The sixth target is a massive dam and reservoir in Idaho, which resulted is several children and their parents' deaths. The FBI have formed a huge Green Man Task Force but as yet they don't have any clues to the bomber's identity or whereabouts.

Tom Smith is a young computer analyst with the FBI. His father, a retired FBI man himself, has great difficulty in expressing any pride in his son; nothing seems to be good enough for him. Tom is supposed to be at the bottom of the FBI "heap", he's young and inexperienced in FBI work, but incredibly clever when it comes to finding patterns hidden amongst computer data. After inadvertently drawing attention to himself in a briefing one day, headed by the boss, Jim Brennan, he finds himself in the Assistant Director's company and allowed to speak his mind about the direction the Taskforce is taking, resulting in an inordinate amount of freedom to chase his ideas.
Tom works to get inside the mind of the bomber, calling into question the standard FBI profiles and gaining respect from his co-workers.
But Tom is fundamentally torn - he will do everything he can to capture the bomber but, on the other hand, he has sympathy with the environmental cause - will he be instrumental in the Earth's destruction.

The Green Man hates what he feels he has to do. He is particularly concerned about the loss of life, particularly children, which he has caused. It affects him very badly and he privately grieves for them.
Just one more attack to be made, then he can disappear forever.
However, Tom is continuing to think outside the box and is getting ever closer, despite the bomber laying a complex trail of mis-direction to escape capture.

Intriguing, absorbing and thought-provoking. Great read.

This was a very good read and one I would recommend. An excellent thriller about topical issues. I have not read any books by this author but will definitely look out for them in the future.

This was a fast paced thriller with a theme of environmental issues and one man's journey to make those in power take notice of what is hallpening to our planet. It would make a brilliant film or tv series as it is a thrilling in every way with topical issues that are at the forefront of life at the moment and different points of view from the green man to those who are affected by his actions..

An interesting take on environmental issues and the politics of terrorism wrapped up in a page turning thriller

Absolutely loved this tale. Fantastic characters and excellently reseached in terms of toady's climate and the horrors that await us if we don't act now and how we should have acted far, far earlier. Great hero / antihero and solid detective work make this a book that many will really enjoy.

Highly recommended

A environmental activist , The Green Man, goes on a spree to highlight the dangers to the planet of fossil fuels . He has decided on 7 big explosions to large sites to bring notice to these dangers . The FBI tries to trace him but there is little evidence to find because he has covered his tracks carefully. A computer programmer is brought in to create a profile of the killer ,because of The Green Man's apparent engineering knowledge and thoughts on the environment.. There follows a dramatic case to narrow his identity down and it ends in a spectacular showdown in a fracking site . Very good story , if a little preachy, just hope it doesn't give anybody any ideas.

An excellent thriller. This was highly enjoyable and very fast paced. I enjoyed the settings, and cat and mouse game between the investigators and perpetrator. The writing was clever and anyone who loves thrillers will not be disappointed.

In this serial killer turned environmental activist book, in which the killer is intent on saving mankind through his inconceivable deeds, The Green Man, so dubbed by the media and the FBI pursuing him, doesn’t kill for the sake of some insatiable, perverse sexual desire but out of an acute calling to save the environment.

By targeting certain sites, the Green Man’s terrorist acts are meant to call attention to climate change and heighten awareness of its adverse effects. The novel opens with the destruction of a dam on Idaho’s Snake River. Environmental activists regard his actions as heroic, despite the deaths incurred along the way which the Green Man views as collateral damage.

FBI data analyst Tom Smith and a task force of 300 FBI agents only see a killer who must be stopped. Smith brings to the investigation an outside-the-box approach, as he realizes that the killer isn’t just some deranged sociopath killing for kicks or sexual gratification but may be a well-educated, well-adjusted family man whose cause is more important than a few unfortunate deaths. So begins a fast-paced game of cat and mouse as Smith zeroes in on the Green Man’s identity, intent on stopping him before more lives are lost.

This was my first David Klass book and definitely not my last. It has been a long time since I last read this genre but I really enjoyed it. This book is about saving the environment but going the wrong way about it, I loved Tom Smith, such a generic name for what seems to me is going to become a great lead character in future books. I would definitely recommend this book.

Who is The Green Man, a very clever and knowledgeable environmentalist. The only problem is whilst undertaking his environmental bombings he is killing innocent men, women and children. Tom Smith followed his father into the FBI, he is a very accurate profiler. He has worked out who The Green Man maybe but they need to know if anyone is helping him. The Green Man plans his journeys on back roads, when no one is around to see or identify him. Everyone, even the unibomber eventually makes a mistake, will he. Who is he and where does he live. Terrific book which I really enjoyed..

Very pertinent, especially with the positive environmental effects the lack of industrial activity has had on our planet, due to the current pandemic; this will be a call to arms for some and a difficult protagonist to dislike for many.
Obviously with a similar American president to reality (there's a very telling little paragraph about him contemplating his mortality towards the end of the novel) and sympathetic FBI agents, many with superlative intellects, David Klass doesn't give us the typical good versus bad, bright versus plodding set up.

Every character plays their part and you find yourself wanting to know more about Tom, obviously, but also the local traffic cop with an army background who finds himself at the centre of the biggest nationwide manhunt, thanks to a faulty tail light. The engineering professor in a loveless marriage and the idea of a retired Brennan, if that's even a possibility.

The tale speeds along at a brisk pace and the tension is maintained well with the reader privy to both Green Man's activities and Tom's long FBI leash as he follows his data-crunching smarts.

There were a few off-putting, awkward sentences at the beginning of the book but it soon settles into a good old cat and mouse chase and I'm glad I persevered.

The author mentions his inspiration was conversations with his teenage daughter - let's hope he is further inspired by his family to write another current affairs nailbiter. 'Brexit - the epic' perhaps, Mr Klass?

An interesting theme that is particularly relevant to the present time. Keeps the reader involved and definitely recommended to those readers who enjoy reading this type of book.

The main premise of the story is a young FBI agent, Tom, and his pursuit of a modern terrorist, The Green Man, committing crimes in the name of protecting the environment.

The characters are well crafted and I enjoyed the personal conflict they both faced but I didn't really warm to them as individuals which was unfortunate.

The thriller is well-paced although there are times where the text feels like a hidden lecture on climate change.

Not my usual genre but I was gradually caught up in this topical story of Greenman attempting to save our planet but causing mayhem for the FBI,. Some of the characters were very true to life, some definitely more than others! Loved the personas of profiler Tom Smith and Greenman both battling with their different but similar consciences, Found it difficult to let go of the story but the conclusion was right and proper and enjoyed immensely! Would make a great film!

A thriller which is difficult to put down. Dual narratives - by Green Man, the eco warrior who is gaining cult status in the United States and Tom Smith, a young but brilliant FBI agent who is known to think successfully 'out of the box'.
Green Man puts forward a compelling case with a stark warning about how we abuse Planet Earth and its consequences. Whilst Tom Smith is dedicated to catching him and preventing any further eco-terrorist attacks, he feels an natural empathy with his opponent.
A brilliant book, a satisfying conclusion (it could be no other way!) An excellent choice for a Book Club as it will provoke varying responses from members, leading to fascinating discussion.

Loved this book from the first to the last page. It kept the anticipation up until the very last moment. I would highly recommend this, easy read, page turner.

I very much enjoyed this fast-paced thriller, which had me hooked from the beginning. The story of the Green Man, trying to save the planet but committing crimes along the way, and the FBI analyst, Tom Smith, out to get him before he causes more havoc. Smith has many obstacles in his way not least the fact that his father was also an FBI agent.
A very topical subject, climate change, and a particularly good read. I would recommend it.

This is a fast-paced thriller that addresses environmental issues and terrorism. The FBI is in a race against time in a search of a serial bomber before he hits his next target and kills more people. Tom Smith is an analyst and it seems he is the only one who understand this terrorist. Will he finds him before the next bomb goes off?

I had high hopes for this novel and for the first half it was okay, but then I started losing interest and the end was a bit of a disappointment. I didn't like how both the characters and the story developed. This is only my personal opinion as I saw that many people ejoyed it, but it really wasn't for me.
