This is the first time I had such a negative reaction to a book! I would read a few pages at night before sleeping, and then have nightmares! Well, the thriller part could have been more fast paced... I felt the story drag on in the middle. The tale is different, but could have been told more effectively. And even though she goes through a lot, you don't really connect too well with the lead character Jenny. If you ask me, she's too weak and helpless! All in all, I'd say you can give this one a skip..
Now I need something cheerful! Maybe I'll pick up my Wodehouse or Douglas Adams again!
