The Quantum Grail

A former Navy SEAL risks it all to find his missing wife, leading him down a deadly road of governmental conspiracies, technological warfare, and dark secrets from his own past, in this debut page-turning thriller for readers of David Baldacci, Harlan Coben, and Blake Crouch.

John Mitcham is clinging to a photo of the family he no longer has. What he does have is three crucial pieces of information:

There is a CIA safe house in Northern Virginia.

Inside it is a woman who created a horrible thing.

That horrible thing is John’s only hope of finding his wife.

When John storms the house and extracts Nia Banks, he embarks on a run from the CIA with the world’s most notorious hacker. She’s also the creator of the Quantum Grail—a secret CIA supercomputer that has been stolen by a clandestine syndicate. The same syndicate that abducted John’s wife and four of her psychiatric patients for spine-chilling reasons.

Yet no lesson from decades of warfare has prepared John for what lies ahead.

The world he knows is already gone.

With breathless pacing and riveting suspense, The Quantum Grail is a story of how far we’ll go to overcome our greatest regrets and unfathomable forces to save those we hold dearest.
