Twenty-five years ago, an SAS patrol found something on a remote Bosnian plateau that no one was ever meant to see. Cameron Hayes was there. He just doesn't remember it.
Now he has a tumor in his brain and a cocktail in his hand, and retirement in San Diego is as quiet as he ever wanted. Until his closest friend is shot dead in front of him, the killers turn their sights on Cameron, and a woman he has never met tells him she knows exactly who he is.
She says he once served with Trident, a covert program guarding the oldest secret on Earth: ancient, sentient Trees that have hidden since the planet was born, and the rare bloodline that can wake the power inside them. Now a rogue scientist has gone looking for that power. And the one man who might stop him is running out of time, and out of memories.
From the beaches of San Diego to the frozen edge of Iceland, Believing Trees is a relentless blend of military thriller and mind-bending science fiction, for fans of James Rollins and Douglas E. Richards.
Book 1 of The Penumbra Files.
