It is Persephone's birthday, and she receives the ultimate gift: Hades confesses his desire for her, leading to their first kiss. But that doesn't necessarily make things easier for the goddess of spring, who is still in over her head in gossip-driven Olympus. Persephone feels intense guilt over the official breakup between Hades and Minthe, she is struggling to find her footing in her fast-paced job, and--worst of all--the shades of her past are slowly coming to light. After an unexpected encounter with Apollo, Persephone flees into the depths of the Underworld. Concerned for her safety and determined to find her, Hades must team up with Artemis, Eros, and Hera, but they're working against a ticking clock. Zeus knows about the bloody secret in Persephone's past, and now the furious king of the gods will stop at nothing to bring her to justice.
