Mal is back—but nothing is the same.

Ciara won't look her in the eye. Kimmy is acting like Mal is going to murder them all in their beds. Ginevra is too friendly all of a sudden. And in the wake of Mal's crimes against Persephone's temple, relations between Hades and Persephone are growing more strained by the day.

When an unexpected attack strikes at the heart of the temple, the rift between Hades and his allies widens—and the bonds between Hades's operatives begin to fracture. The deeper Mal digs, the less she understands her enigmatic enemy, and the more she discovers that everyone has something to hide... including her. As she tries to outthink a foe whose actions make no sense, she doesn't know who she can trust anymore—or who will make it out alive.
