Tom Keeler came to Miami for one keep his friend alive while Dave faces his demons. The Delta Force operator's PTSD is so severe that even experimental therapy feels like a last resort. But when Russian organized crime starts watching the house where Keeler's staying, a simple security detail becomes something deadlier.

The surveillance isn't random. Keeler's friend Blomstein works intelligence contracts tracking dirty money through Miami real estate - work that makes enemies. Now those enemies are moving, and they're not alone. A private military contractor with its own agenda is hunting the same Russians, and Keeler is caught in the middle of a shadow war he doesn't fully understand.

As assassinations escalate and betrayals multiply, Keeler must protect Dave through his most vulnerable moments while navigating a landscape where no one is who they claim to be. The Russians want blood. The PMC wants control. And somewhere in the chaos, the woman Keeler's falling for might be the most dangerous player of all.

In Miami's heat and violence, loyalty becomes the only currency that matters - and the most expensive thing to spend.

A military thriller about friendship forged in combat, tested by trauma, and hardened by fire.

Backlash is the eighth book in this excellent series featuring ex-special forces operator Tom Keeler. He is in Miami to support his friend Dave (ex-Delta Force) who is about to undergo experimental treatment for severe trauma resulting from a mission that ended badly. Keeler is house-sitting for another friend, Blomstein, who is currently in the Cayman Islands with his girlfriend, though not on holiday as he led everyone to believe.
Keeler is unwittingly drawn into a conflict between the private military contractor that Blomstein is working for, and a Russian organised crime gang. The plot is complicated and because of this the first few chapters are slow as all the elements are introduced. This does not last long. Soon the tension is palpable and Keeler’s life is under threat from all sides. The characters are well drawn and entirely believable including some colourful supporting ones.
I have been a fan of this series right from the beginning, and it just keeps getting better and better. While you could read Backlash as a standalone, I suggest you go back and read them in order to get the best experience. Keeler has now become my favourite ex-special forces action character (since Scott Mariani made the devastating decision to retire Ben Hope) and I look forward to many more books in this thrilling series.

I discovered Jack Lively and his Tom Keeler series six years ago and was hooked immediately. Backlash is the eighth adventure in the series and it's filled with twists and turns and some great action. Tom is only supposed to be in Florida to help an old army buddy handle his ptsd, sounds simple enough. While there he stays at another buddys place and strange stuff happens to him there that leads to his involvment in a turf war between a security company and some eastern Europe gangsters. At the same time his friend with the house is on a mission in the carribean. I found the story well written and intriguing and I can really recommend this book. I do however think that you should start from the beginning. I must thank the author for sending me an advance copy.

*spoilers* I love these books, this one resonated more than usual

As I suffer from severe deep seated PTSD and none of the conventional theraies have worked for me either. I thoroughly enjoyed the book from two points of view in the good old Keeler thriller and the potential therapies even off books that may be available to people who have suffered severe mental trauma. I'd love to know how my brain lights up or the hyperbaric chamber to help myself and others (I'm not in the USA though and NZ is so far behind in therapies and drugs for these things). Anywhoo can't wait to see what keeler has in store next but maybe just maybe let him get the girl and let him settle down sometime?

Tom Keeler one man army again

The body count is high, the risks too, the plot is complicated. Two unassociated criminal organisations with lethal capabilities both fighting for the same prize, means Keeler has to manage a tricky balancing act, being caught accidentally in the middle. Although he’s as deadly as usual, he does suffer a few attacks - staying alive feels like a miracle in itself at times. So far, his ‘retirement’ looks just as busy as his previous job in the military.

On par with Clancy & Ludlum

Backlash is the best yet from this author. It has the technological accuracy of Clancy and the nail biter thrill of Ludlum’s Bourne series. If you want the best, look no further. All thumbs up. Bravo!

Another side

In this book keeler showed a softer side and he was funny. You could see how much he valued his friendship with the guys he served with.

Lively sends Keeler on another mission…

Leave it to Keeler to arrive in Miami for one reason and end up with several things to occupy his time. Some of it good. Some not so good, which is more typical. It is a thriller, after all. Add to it a couple of new characters important to Keeler from his military days and things get really interesting. Sometimes it’s difficult to tell who the bad guys are so when things go FUBAR, Keeler and his tried and true buddies always have a plan B, and C.
I like the new characters and how they mix with the plot line. I hope they make a return in future Keeler books. I’m especially fond of Dave. I for one would not be disappointed if he spun off into his own series. Looking forward to the next Keeler thriller!
