Amanda, a half siren demigod, is tired of assisting her mother and the other sirens in drowning men by singing, so she runs away to a nearby ship where she becomes the only female crew- member. She hides who she really is and tries desperately to forget her past and move on with the future. Now 14 years old, Amanda's life couldn't be more perfect. Captain Joyce has taken her under his wing, and she is now an official crew member and 'one of the guys.' The only one who knows about her terrible past is Jeremy, her best friend. But when Captain Joyce discovers her true identity, he kicks her off the ship. Jeremy accompanies her, a true friend. But when Apollo and Artemis appear to the pair and assign them a quest, they may just discover a little bit about love, who they are, and what they're capable of.
