A  New York Times  and  USA Today  bestseller! In this dark and sultry romantasy a mermaid battles hatred—and lust—for the wretched warlock who saved her life.  Mermaid Zephyra of the Syl dreams of freedom. On the run from a dangerous captor and years of abuse, she’s shed her tail, grown legs, and hidden herself on land in the merrow-loathing kingdom of Mortia, left to steal and barter on the dirty streets. But her freedom is short-lived when she’s caught and sentenced to death by the brutal warlock, Arion Stone.  Arion is as beautiful as he is cold and deadly, only interested in punishing the merrow he views as evil. He has grown as strong as any warlock might, but at great personal cost ... which can only be remedied by the heart of the God of Death, lost to a fabled kingdom beneath the ocean’s treacherous depths.  So Arion offers Zephyra a deal she can’t refuse; help him find the mystical heart, and he’ll spare her life. With no other options, Zephyra agrees, entangling their souls and forbidden desires in a magical bargain until death do they part. But Zephyra's past is catching up to her, and the enemy she fled seeks vengeance. If Zephyra and Arion can't learn to fight together—and trust each other—there are worse things awaiting them than just death. Of course, in the wicked sea, everyone has secrets, and no one should be trusted.  Perfect for fans of: Enemies-to-lovers Magic  Sensual Bonds  Winged Romantic Leads Forced Proximity
