How do you piss off a god? Eliana Porter has no idea, but she'd better figure it out. Quickly. After a trip to Greece goes horribly wrong, Elli finds herself in over her head- literally- with curses, kings, monsters, and immortals, all buried in the depths of the Aegean Sea. With her mysterious new ally Atticus keeping her annoyingly in the dark, Elli must untangle one of the ocean's oldest secrets, before she and her friends are swept away with the unforgiving tide.
