Falling for the Beast by Victorine E. Lieske

Aribelle is backed into the position of cleaning house for the horrible Mr. Thaddeus Walker. Not only is he rude, he’s dangerously secretive, going out at night and coming home with injuries which seem to heal mysteriously fast. She should be keeping her distance, not trying to break down his barriers. But the more she uncovers, the more attracted she becomes until the cost of exposing his secrets fades behind the risk of losing her heart.

Thaddeus knows he should have sent the girl away instead of allowing her into his home. Now she’s asking questions he can’t answer. And the more time they spend together, the more he wishes he could pull her close and kiss her. But he can’t afford to do that. Beautiful Aribelle could never love a beast.
