ONE MYSTERIOUS DISAPPEARANCE. ONE MYSTICAL CLUE. When Caitlin O'Shaughnessy's stepfather — world-renowned Medieval English professor Magnus Armstrong — is abducted in Scotland, she jets across the Atlantic to help find him. Her only clue: a teardrop-shaped charm on a broken chain left behind in the struggle. The authorities in Edinburgh are useless, but Caitlin soon finds a partner in her desperate search — sexy playboy Dominic Fortune, who's funding genetics research at the university. Traveling to the Mediterranean island of Calix, where the charm originated, they share a journey full of danger, passion, and magical surprises. But Dominic carries with him more than a few secrets — about his identity, about the dynasty that has ruled Calix for more than 2,000 years, and about the charm's link to the quest for eternal life. Racing against time and surrounded by people she's not sure she can trust, Caitlin must use all her wits and an ancient magic to save her stepfather and herself and to uncover the many mysteries of the man by her side.
