Thrown off of a ship, drowned, and brought back as a siren. Ilara can not believe this world of destinies and "fish-women". But when she's asked to kill, as is their purpose, and convinced that it is the right thing to do, she struggles with her first victim. What she doesn't know is a siren's first kill is who was supposed to be their human soulmate. Will she slaughter him in cold blood? Will he be daft enough to get close enough to her?
