Emma's family was gone, and suddenly, all she had to call home was a boy named Alexander Keith. From the moment she met him, as a little eight year old trying to get over the death of her loved ones, he had been there for her. Now, many years later, he still is. But just as they are about to turn seventeen, something changes. She is thrown into a world of fairies, vampires, and werewolves. Of whom turns out Alex is alpha. So what will happen when her past comes bursting to the surface, and she is left in the middle of a century's long battle and a very powerful wolf who would do anything to protect her?
