His to Keep by Lydia Goodfellow

Stolen in broad daylight on her way home from school, for Ava Hanlon, the nightmare is only just beginning. So young and achingly naïve, Ava is no match for her depraved new master, Father Mathew Aaron, a well-respected priest, and a man hellbent on consuming her innocence to the very last drop.

There is no hope. No light. There is only Callum. A troubled, tormented young man imprisoned in the same room as her. As each day slips by without rescue, all that is left is this fierce, dark entity stirring between them—something far more threatening to her virtue than even Father Aaron’s obsessive game. Something so powerful, it may just make her want to stay for keeps.

A dark psychological romance that’s full of twists and turns you won’t see coming.
