Paige is a chunky, shy, poor girl who is totally loveable. I just wanted to scoop her up and hug tight. She is thrust into this dangerous situation and fights as best as she can. Donnie is harder to like. He does some horrible things that made me weary of liking him. He is redeemed as the story progresses. So, why not 5 stars? The first reason is the time lapses. A year passes, a month passes, ect. It's jarring and we don't get to see how Donnie and Paige bond. The second reason is the editing. I usually let that pass but this is pretty bad. Repeated phrases that are only a paragraph or two apart and odd sentences that really push me out of the story. The third and most important reason for three stars is the sex. Yup, the sex scenes are hot but 3 in a row is too much. I was bored with them and then the author added two more spread out after that.
Overall, I think Stepbrother's Debt is a good read. If you can find it on sale I'd say to give it a try!
