I do not wish to anger any of the gods--new or old.
A year after Atlanta and Damien were brought together by the Pythia, they are once more called together. This time, by their old friend, and the new Pythia--Calista.
All around the Mediterranean, there are strange storms, mysterious disappearances, and gruesome murders. Though the events are seemingly unrelated, Calista believes they are the work of an angry god.
She tasks Atalanta and Damien with putting an end to the destruction. Alongside old allies and new, they must face sea monsters, pirates, fearful mortals, and sirens.
Whether their truce and fragile friendship can survive the journey to find, and stop, Poseidon, is a risk they must take.
