A mermaid in disguise. A soul-stealing pirate on a mission. Two worlds destined to collide.

When sea-knight Siddhe left the mermaid kingdom of Celantris, she had one mission; find the infamous Captain Elian Westin and convince him to break a devastating curse. Instead of fighting in a war beneath the sea, she takes the role of an innocent tavern keeper as she hunt for her prey.

Once their paths meet, she finds herself falling for him and in danger of shifting alliances. Her heart wants one thing, and her duty demands another. But when Elian's rival begins dealing with dark magic, both of their worlds are in danger.

Siddhe must tame the pirate, save her people from a curse, and discover her true power in this swashbuckling enemies-to-lovers prequel to Half-blood Dragon.
