I think it is interesting to note that (at the current time) there are 915 reviews for 50 Shades of Grey but only 100 for this one! I read the first one and despite the poor writing skills and the almost laughable repetition of words and phrases, I quite enjoyed it. The character of Christian is quite well defined and I actually found myself fancying him (although I don't think we needed to be told how 'beautiful' he is on every single page). On the other hand the character of Ana is as wet as a lettuce.
This second book is just 300+ pages of soft porn mixed with Mills & Boon mush! Once again the level of repetition is beyond belief - I strongly recommend that the author buys a thesaurus. However, let's be honest, no one is buying this book for its literary appeal. The sex scenes are pretty much constant in this book but once you have read one you really don't need to read the rest. I actually found myself skipping huge sections because I was just so bored of their shenanigans. The best bits of both books are the emails between Christian and Ana.
I cannot face the 3rd book so I have have a run down of what happens from a friend who has read it!
