"History is full of secrets. Secrets that have remained hidden for thousands of years. And we have no idea what many of them are. We know they're there, under the ground, at the bottom of the ocean, hidden away, just waiting for someone to unlock them." Enter Jack Howard, one of the greatest archaeologists of his day, a man who never stops believing, never gives up hope that out there might be the next big discovery. But when he and his best friend Costas are interrupted during a dive off the coast of Sicily that might possibly reveal the final journey of St. Paul, Jack has no idea what lies in store...Their journey takes them to one of the great lost libraries of antiquity, destroyed by the eruption of Pompeii, into the heart of ancient Rome and the holiest sites of Jerusalem.
