Call of the Siren (Call of the Siren #4)

The song reaches its end! Deep within Tartarus, Gemma faces Hades and the truth of what she is. As her mother’s voice fades into myth, a choice must be made. Will Gemma cling to what was lost, or become something new? But Hades does not rule the underworld alone, and the forces gathering around Gemma are older and far more dangerous than she understands. As the gods move openly, alliances are tested, sacrifices are demanded, and the line between fate and identity begins to collapse.
