how to explain such a success?

I do not understand the success of this book. Do we need the approval of the group to buy an erotic book? I must confess that I stopped along the way so I found the boat history and without style. A naive young girl, modest and virgin falls under the spell of a beautiful man, rich and powerful who incidentally loves love sadomasochistic .... oh oh But her best friend was warning against the Christian beautiful whose reputation and the secrets outperformed. It is "fascinated" read the detailed descriptions of all things luxurious and expensive that have this man. Between cars, helicopter and stays in luxury hotels ... the young and naive young girl falls in love. The erotic scenes save the book whose history is not worth a copèque!
