I would have to concur with most of their choices.
Explicit, yes. However, the character development prevented me from putting these down. You will certainly find yourself skimming over the 'explicit' just to get on with the story to try and understand this couple. It's been a fun read, better if you have a friend to talk to about it because it's hard to explain why it is addictive until you pick it up for yourself.
Next book series I'm gonna read!
