She thought that life in a new town would be boring; boy, was she wrong! Fifteen-year-old Ruth Daniels has never had a lucky break due to being a lifelong orphan living in Michigan, but she ends ups going from a orphan to a family girl after she gets adopted by a widowed Businessman and moves to New Jersey to live with him and his family, including a stereotypical teenage brother, a snobby sister and two twins. Yep, that's all there is to it. Soon afterward her arrival, she starts school and almost instantly ends up with two new friends: Rachel Evans, a redheaded senior, and Justin Reynolds, a quiet, lonely and withdrawn sophomore. The latter of whom Rachel seems to hate with a vengeance. As Ruth and Justin's friendship begin to evolve, Rachel starts to stalk and attack them almost constantly, and Justin knows why: He's a human/animal hybrid called a Preevitt, he and Rachel are longtime mortal enemies, and Ruth is now part of their longtime war that also includes Justin's twin siblings, Jaz and Wheeler.
