In a war between the humans and the inhabitants of the sea-humans will lose. Xanthus Dimitriou-the most lethal Dagonian to rise from the ocean-is on a mission to save mankind from annihilation. But first there's one small thing he needs to do... kill a beautiful young woman in a wheelchair. 

Killing her doesn't start out as part of his plan. He entrenches himself deep in the human world. Aligning with his enemies, he prepares to send them to Triton to face their punishment. Then Sara Taylor rolls onto the scene. Xanthus knows at once she's a criminal. And her crime? Being born. She's a human/Dagonian half-breed, an abomination. Killing her should be an easy job. All he has to do is break into her apartment, slit her throat, and feed her body to the sharks. Simple, right? Wrong. If only she weren't so beautiful, so innocent, so sweet... Saving the world may have to wait. It appears Xanthus has a woman to save. But protecting her may cost him his own life.
