Provocative reading

Some days ago my sister gave me this book. She got it as a present from a friend, started reading and couldn't go on. As I just finished my book and had no other at home I started reading.

Only three days and I finished it. My conclusion? Of course it is a very provocative reading and some of the described scenes are really a little bit "hard". Is that the right word? But all in all I like the spirit of the book. And I love the broken taboo.
