This book is inspired by the german fairy tale called Undine. I borrowed this book from the library because I thought that it sounded interesting, but it was even better than I thought it would be. I got sucked into the book and read it all in one day.This is an amazing story of love, and terror. It will suck you in and keep you reading because you want to find out what is going to happen next. It sucked me in, and now this book is one of my favorites.
