Bestow the Darkness by Amanda Hocking

BESTOW THE DARKNESS is a brooding gothic romance set in the rugged forest of 1890s Michigan. Emiliath lives in a cloistered religious sect with her sisters and brothers, as she has for over twenty-one years. Her life is stable and quiet, but she has begun to feel a longing for something more. When tragedy hits close to home, she begins to connect with a handsome stranger from the city, Trent. But her quiet life is far more sinister than it seems, and Trent has his own secrets. On top of that, a hungry beast is lurking in the forest, and it might be the end of everything Emiliath has ever known.
