So the Ocean is alive and needs to eat humans to continue to live. If humans don't drown because hurricanes, mechanical failures on boats, or other natural disasters the sirens come in. Their job is sing the people to their deaths, to feed the Ocean. This book is about one siren in particular, Kahlen. She is on a boat that is being sung to by sirens and she wants to lives so she becomes a siren. With 20 years left of her 100 year sentence she meets Akinli. He doesn't care that she's mute and he sees more than just how beautiful she is; he sees her. She starts to fall in love with her so she and her siren sisters move away. But she isn't handling it well and she goes into a depression so the keep moving and keep moving. Well, the time comes where one of the siren's is at the end of her 100 years and it's time to add another siren and they find her; her family tried to drown her just for being a girl. Kahlen is having a hard time with all of the death she causes and she runs away and ends up with Akinli after not seeing him for months. They kiss. She talks. He tries to drown himself. She pleads with the Ocean to save him. He is saved. She leaves and she tries to be a good siren and a good "sister" but the next time they have to sing she almost drowns, and she can't sing. Then she starts getting sick which shouldn't be possible. Come to find out, he is sick too. The sisters think something happened to him and he gave it to her, but then the remember that she's more than human and start looking into siren myths. Turns out that her voice poisoned him and that he is a siren to her. That they are connected. The only way to save him is to save her. So the Ocean turns her mortal again. Her sisters leave her at his cousins' house. She has no memory of anything (that's what happens after you are no longer a siren) and they both start getting better. It was sweet. I understood how Kahlen would have trouble with the death and destruction she was creating. How she just wanted to be obedient but how hard it was. And how she just wanted to have a life. How Akinli gave that to her and she tried to resist it; she tried so hard to be good. Once it was all out in the open; once her sister's knew how much she had been suffering and hiding for them, once the Ocean knew how much she had been hiding to be good for her, it was a relief. That they were each others sirens was a nice touch. This was not as good as The Selection Series, but it was still enjoyable.
