Eternal life. Eternal battle. Steve—Diomedes Tydides to his Trojan War buddies—just had a bad day on his charter fishing boat in San Diego, but when the goddess Athena calls on her faithful warrior for another secret mission, he’s ready. The bomb that exploded inside the Metropolitan Museum of Art isn’t the crime American authorities think it is. Someone also stole the Cup of Jamshid, and Diomedes knows its fortune-telling abilities won’t be used for anything benign. Though Diomedes recovers the Cup from a determined shaman holed up beneath Central Park, when he finds his allies slain and the Cup taken once more, he knows he’s up against a truly powerful enemy. Over a millennium has passed since Diomedes last contended with Medea of Colchis, deranged wife of Jason the Argonaut, but neither her madness nor her devotion to Hecate, goddess of witchcraft, has waned, and she intends to use the Cup of Jamshid to release across the world a dark brand of chaos unseen in human history. Immortal since the Trojan War, Diomedes must once again fight for mortals he understands less and less, against a divine evil he may never truly defeat.
