Banished, book 2: UnforsakenSophie Littlefield2011

Hailey Tarbell is no typical girl. As one of the Banished who arrived from Ireland generations ago, Hailey has the power to heal - and, as she recently learned, to create zombies if she heals someone too late. But now, Hailey is finally getting a chance at a normal life. After realizing the good and bad sides of her power, Hailey has survived the unimaginable to settle with her aunt, Prairie, and her little brother, Chub, in the suburbs of Milwaukee. Finally Hailey has a loving family, nice clothes, and real friends. But her safe little world is blown apart when she tries to contact her secret boyfriend, Kaz - and alerts the incredibly dangerous man who's looking for her to her true whereabouts.
