The Neighbors by Ania Ahlborn

Andrew Morrison sacrificed everything--is childhood, his education, and the girl of his dreams--to look after his alcoholic mother. But enough is enough, and now he's determined to get out and live his life. That means trading the home he grew up in for a rented room in the house of an old childhood friend--both of which are in sorry shape. The only thing worse than Drew's squalid new digs and sullen new roommate is the envy he feels for the house next door: a picture-perfect suburban domicile straight out of Norman Rockwell, with a couple of happy householders to match. But the better acquainted he gets with his new neighbors--especially the sweet and sexy Harlow Ward--the more he suspects unspeakable darkness beyond the white picket fence.
