Carys Jones, a rare book authenticator, lives for the thrill of uncovering ancient manuscripts. When her wealthiest client is committed to an asylum, he offers her a deal she cannot resist: his entire library of priceless Dark Age texts in exchange for solving the clues in a mysterious journal.
The journal points to a hidden tomb that could rewrite the history of Western civilization. But others will stop at nothing to keep its secrets buried.
Her hunt takes her to Wales, into the arms of Dafydd, a mysterious ally with secrets of his own, and into an unsettling partnership with the ghostly monk who penned the journal 1,500 years ago.
Some histories change the world. Others are dangerous enough to kill for.
