Whoa I'm almost through the first book. The relationship in this book is serious unhealthy. I can't believe this is the most popular book at the moment.
Spoiler:
Forget the How To BSDM guide in the novel This Christian guy has every red warning light a girl or women should stay away from. He is a stalker psycho. Serious unhealthy. She leaves to get some space and he follows her.
There is nothing romantic or erotic about this. Anna needs to seriously get away from this guy. She's like plenty of young girls with low self esteem and she can't see this guy for what he really is.
I'm waiting for this to turn into a thriller lifetime movie.
