Every spring, Ithaca condemns twelve virgin girls to be hanged. This is the price that vengeful Poseidon demands for the lives of Queen Penelope's twelve maids, who were hanged and thrown into the sea a century ago. But when Leto is chosen, death turns out to be different from what the girl imagined. Instead, Leto wakes up on a mysterious island and meets a stranger with green eyes and power over the sea, a girl named Melanto, who says that only one death can stop a thousand. The prince of Ithaca must die otherwise, the waves of fate will drown them all.
