Fifty Shades of Grey

I am reading this online version if the book right now. Completed a third of it, so far so good. The main theme of this book is about bdsm and so far i hasnt read much about it yet. It's a page turner though... I nv want to put down the book! I guess i just want to know how creepy christian grey can get...and the extent of anastasia's submissiveness. This book is so enticing indeed!
