"A priestess by birth on the Bronze Age island that is now Santorini, Leira finds her coming-of-age training cut short when an earthquake destroys her town and leaves her powerful mother disabled. Warned by an oracle that worse is yet to come, the family flees to Crete but finds no sanctuary. A tsunami sends the island into anarchy and Leira must hide her noble status and learn new kinds of strength to help what remains of her family to survive."--Provided by publisher.
