The title of the book that I suggested to you is called "Medianoche". It's a book very interestant. It treates of a romantic story between two teenagers. The girl of this story is a vampire and the boy is a hunter of vampires but they didn't nothing about it. So they are enemies but love can win hate and the vengance. This story have action, emotions, adventure, mistery and intrigue.
A curiosity of this book is that have a continuation . The second book of this saga called "adiccion" and alsois incredible.
