Going Grey

2014

An all-original near-future military thriller from the #1 New York Times bestselling author! Who do you think you are? Ian Dunlap doesn’t know. When he looks in the mirror, he’s never sure if he’ll see a stranger. After years of isolation, thinking he’s crazy, he discovers he’s the product of an illegal fringe experiment in biotechnology that enables him to alter his appearance at will. And the only people he can trust to help him find out who and what he is are two former soldiers trying to make their way in the high-stakes world of private security. He’s got a unique and disturbing skill: they can help him to harness it—and maybe even learn to accept it. Set ten years from today, these three unlikely allies search for identity and loyalty in an uncertain world.

Black Run

2017

The past doesn't forgive. The past doesn't forget. And it knows where to find you. Rob Rennie's life hasn't got any quieter since he left the Royal Marines and teamed up with an American vet, Mike Brayne. Mike – eccentric, idealistic, and enormously wealthy – can't resist righting wrongs. He's rescued a genetically-engineered teenager on the run from an experimental defence programme, brought down the head of the biotech corporation hunting the boy, and now he's waiting for the company to make another move, if it dares. But Rob lives by the maxim that there's no such thing as over. And something's certainly not over for him. An unknown, unseen enemy is stalking him, with tragic consequences for his son and ex-wife. As Rob and Mike close ranks to protect their families, they find themselves up against industrial espionage, two warring scientists, and a blood feud that won't end until somebody pays with their life. The buried past has been biding its time to explode beneath them. Now their best hope of putting it to rest forever could lie in the unique genetic skills of a runaway teenager.
