~ Happy reading ~
You have to read this by yourself. (5 star rating from march 2012)
UPDATE (october 2013)
After reading a lot more erotica I feel more ambivalent about this series. The books are fun to read but really Ana get some balls (not literally but she should have stopped being such a wimp during the books). After reading two quarters of the first book the sex scenes between Ana and Christian lost their sparkle and one is glad, to get not so much details in the sequels.
For me it is just an ok read anymore.
