Another book by Kiera Cass. I haven't gotten over The Selection series when I read this book.
It's about a siren named Kahlen. As a siren, her voice is a death sentence to human, and yet she falls in love with Akinli, a human boy who changes her life.
To be honest, this is not a happy-happy love story, so as long as you are in the mood for the somber, emotional intensity of this story, I don't doubt you'll love it as I do.
