As the son of two washers, Jace Kit has only dreamed of adventure—until a fabled Sea Sprite washes ashore and turns his world upside down. The Sea Sprite needs a hero to save the Ocean Queen from a ruthless pirate terrorizing the Remos Ocean. With a legendary trinket and handmade boat to his name, Jace is her only hope—even though he knows the trinket is fake. With Jace's skilled sailing and the Sea Sprite’s magic, the pair enters a competition to win a ship capable of catching the pirate. The only thing darker than the depths are the Sea Sprite’s secrets, and Jace realizes too late his adventure might cost a price too high to pay.
