Elysiel, the last princess of the fairies, risks everything by singing a forbidden song — a melody that summons the most powerful of demons. But instead of meeting her destruction, she receives a dangerous offer: Seraphis, the lord of the underworld, promises to save her kingdom from extinction. The price? Her soul… and her heart.
Now, bound by a dark pact, Elysiel must become queen of darkness. As her fate becomes linked with that of Seraphis, forces beyond her understanding threaten the balance between the world of the living and hell. But as the tension between them turns into overwhelming desire, Seraphis discovers that their love could be the key to salvation — or the undoing of everything.
