Sam Grant, a disgraced ex-Special Operations Executive soldier and an adventurer by trade, is lured back to the Mediterranean by a secret from his past: six years ago, a dying archaeologist entrusted him with his life's work--a leather notebook filled with mysterious notes written in Ancient Greek. Deciphered, it could lead to one of the greatest prizes in history. Which is why both the CIA and the British Secret Intelligence Service are looking for it as well...

Grant sets out to discover the truth about what the archaeologist lost his life for--and to protect his own. Aided by a brilliant Greek archaeologist with her own secrets to hide, Grant is plunged into a labyrinth of ancient cults, forgotten mysteries, and lost civilizations. But time is running out...while a dangerous prophecy is drawing near.
