But her secret is threatened when she triggers a forbidden cross-species Mate Bond with Zayne, the ruthless Alpha King. Zayne is fiercely possessive, while Seraphina tries to hide her identity. When a pool incident exposes her scales, Zayne vows to protect her at all costs. When deep-sea tyrant Dorian brings a deadly tsunami to wipe out the forest, Seraphina awakens her Siren Queen powers.
