Darius Varkas is a drakon. He’s neither human nor dragon. He’s both. He’s also the target of an ancient order who want to capture all drakons for their blood. When fresh, a drakon’s blood can cure any illness and prolong a human’s life, and the Knights will stop at nothing to get it. When librarian Sarah Anderson stumbles across a rare book belonging to the Knights of the Dragon, she’s quickly thrust into a dangerous world of secrets and shifters and things she never would have believed possible.
