Le procès de Perséphone arrive à son terme et le verdict est sans appel : elle est condamnée à vivre dans le royaume des Mortels, loin des dieux, loin d’Hadès. Ni lettres, ni appels, ni doubles coups sur le sol ne lui sont permis. Zeus est le seul à pouvoir revenir sur cette décision mais des révélations bouleversantes lui font percevoir la déesse comme une menace pour son trône. Il préfère plutôt déclencher une guerre froide divine et subir la riposte d’Hadès lorsqu’il ferme la frontière des Enfers. Mais alors qu’un danger encore plus grand rôde sur le monde divin, il se pourrait bien que Perséphone soit la seule en mesure de tous les sauver.

Revelations rock Olympus as Persephone’s trial ends, threatening to throw the gods into a new war. Though Persephone and Hades become closer than ever after she opens up to him about all she has endured, their peace is shattered when another truth is revealed: Apollo is Zeus’s son. The announcement shocks the pantheon, and the king of the gods realizes that the would-be usurper wants Persephone’s power to take the throne. Zeus banishes Persephone to the Mortal Realm and, out of fear, cuts it off entirely from the rest of the gods. This decree succeeds in undercutting Apollo’s plan, but also inadvertently begins a decade-long divine cold war when Hades strikes back by shuttering the Underworld. With the gods scattered and weakened, Kronos uses the ensuing bedlam to finally escape his imprisonment and begin staging his own coup. Persephone has only one choice when she discovers all the realms on the verge of collapse: Descend into the Underworld to try to defeat the power-hungry Titan, claim her rightful place as queen, and reunite with her one true love.
