Iona Night-Singer thought she'd overthrown the gods. Her mortal rebellion eked out a painful victory by using the gods' own powers against them-though she lost her betrothed, Taran, in a final battle with the god of death. Months later, the war doesn't feel over. Not with Taran gone. Especially not when the gods still answer the prayers she sings. Angry, grieving, and with a gnawing dread that the gods will return, Iona strikes a deal with her former patron goddess: if Iona can convince Taran to follow her home from the Underworld, he'll be free to live again. If she fails, they'll both be trapped there forever.
