In Kill Sequence, an action-packed techno-thriller, a desperate man races to find his wife's killer before it's too late, assisted by a sentient AI program planted in his head.

He woke up with a scar on his forehead, a year of missing memories, and a stranger at his door with a warning: "Someone is coming to kill you."

Shawn Nash was supposed to be dead. Instead, he's on the run, and carrying something inside him he doesn't understand-an experimental neural implant powered by the sentient AI his murdered wife created. The world thinks he killed her. Shawn knows the truth, but to prove it, he'll have to find a hidden hard drive with a damning video. Every step of the way, the real killer is close behind... and ready to finish what he started.

Guided by a digital ghost in the shape of a perfectly mannered English gentleman, Shawn sets off on a desperate mission for answers. His journey will take him through the underworld of medicine and the tranquil English countryside, to the cliffs of a sun-splashed Greek island, and deep into a fortified server farm buried beneath the American Midwest. As the bodies pile up, and lines blur between man and machine, he must outrun assassins, outsmart intelligence agencies, and outfight the man who wants to steal what's in his head... and unleash a version of AI no one can control.

But the deeper Shawn digs, the more he realizes:

This isn't just revenge.

It's a kill sequence.

And it's already begun.

"...the global intrigue of a Robert Ludlum novel, and a lean immediacy akin to Lee Child..."

"A globe-spanning techno thriller that does not disappoint. Laced with dark humor, supercharged with maybe the worlds weirdest (in a good way) AI, and the right amount of violence to keep you on edge."

- Lee, Amazon Review

"Thrilling read that keeps you on the edge of your seat, with action-packed scenes and unforgettable characters. The story pulses with energy... A page-turner in every sense."

- NY, Amazon Review

Industry Reviews

" A mindbender/headscratcher/page turner...A stunning debut! From the very first pages, I knew this was going to be a wild ride. Unique, clever, and a whole lot of thrills. This is seriously one of my favorite thrillers of the year ."

Anthony Neil Smith, author of Slow Bear & The Butcher's Prayer

"A thriller with a twist of grounded Sci-Fi...starts with a bang...written in a short, sharp style that really brings the story to life...I will certainly be looking out for more by this author....an excellent book."

Richard Ayre, author of A Life Eternal & The Prophecy Trilogy

"From the first page,I was hooked. Sharp, cinematic, and relentlessly paced. With the global intrigue of a Robert Ludlum novel, and a lean immediacy akin to Lee Child, Kill Sequence races forward on sharp dialogue, intense action, and perfectly timed twists. It's a ride I didn't want to end."

Ronald McGuire, author of the 'Beyond' Series & Nightmares & Lullabies
