The Falling: A New World — S.D. Gripton

Outside the back door of the house-on-the-hill lurks a cave, known as The Beast, who has to be fed one girl a year to fend off an evil spell cast on the family 198-years-ago. Inside it is a throat into which the girls are dropped; to where the family does not know, but if they scream, they die, otherwise, they simply disappear.
