His Brother's Wife by Michelle Love
This is an intense and suspenseful story that is full of drama and angst. Ama has been discouraging Jackson's attentions for years, until her father makes a deal with him that forces her to marry him. Enda is Jackson's half brother, who becomes Ama's friend and ally. And Ama needs one because Jackson is one insane and sadistic bastard. It's an intriguing, but traumatic, storyline that keeps you on the edge of your seat.
I received a complimentary copy of this book from the author. This is my voluntary and honest opinion of it.
