Chaos reigns in Olympus as Zeus publicly declares Persephone a traitor and issues a warrant for her arrest. But Hades defies his brother's decree, sheltering Persephone in the Underworld-and as the pair spend more time together, they are able to speak openly about their pasts. The goddess of spring admits the truth behind the bloody secret that led to Zeus's ire, and the king of the Underworld shares the trauma he suffered at the hands of his power-hungry father, Kronos. But as Hades and Persephone's relationship grows stronger, others begin to fall apart. The bond between Hades and Zeus is stretched to its limit, threatening to fracture the peace between their realms. Persephone and Artemis's friendship hangs by a thread as the goddess of the hunt slowly uncovers the vile truth about her twin, Apollo. A line is being drawn in the heavens, putting everyone's loyalties into question as all the gods are forced to choose sides. And as the cracks in the foundation of the pantheon spread, something darker and more earth-shattering might soon be released.
