Bound by Blood. Samara Hayden

"I would give up Heaven again in a heartbeat of it means you get to live." Samarra Hayden has spent her whole life running from things no one will explain. New towns. New names. New rules she’s expected to follow without question. Mill Hollow was supposed to be just another stop. It isn’t. The shadows close in, her identity is challenged and when the broody bad boy in her new school takes an interest in her, her whole world changes. Caught between a fierce eternal love and a burning desire to belong, Sam must chose if she will succumb to the powers growing inside her, or cling to the angel that has kept her safe, hidden, alive.
