Lord Dalyn Tilden is captured and forced to become a pirate. Having lost everything worth living for, he discovers the seafaring life suits him. The young pirate is content until he learns his shipmates are planning to raid the Fayre Sea Guardians and plunder their legendary treasure. Such a raid is unthinkable by any goddess-fearing Tiaeran, but Captain Jeryn Shadur is ruthless enough to try. As the pirates prepare, Dalyn meets and falls in love with a mermaid, Guardian Minstrel Lyrica Tidalfin. She warns him about the latest attack from the demon god, Ludovique Firebrand. Wrought in the dark elven city of Espion, the harmless-looking, but sinister menace is growing throughout the Fayre Sea, destroying everything in its path. Dalyn refuses to lose another chance at love, even if it's with a mermaid. Unsure how they can ever share a life together, he tries to stop the pirates from raiding her people, earn the right to court her, and join the fight to save the Fayre Sea.
