Despite being just outside of a believable reality, I quite enjoyed Stolen. I felt as though both characters acted in believable ways. The only thing that didn't resonate as a possible reality was Ty's background, which was one of those "nothing could be more sad" sort of scenarios.
What I can say is that during Gemma's recovery, I genuinely felt that I had a window into what someone suffering from Stockholm Syndrome would feel. The only person who knew much about what she had been through was Ty, and he had just risked himself mightily for her, despite previous evil doings. The struggle she felt in deciding whether or not to proceed with a legal prosecution rang true.
So yes, kind of a creepy book, but an interesting look in to Stockholm Syndrome.
