Obsessed with a trilogy

We watched the movie Divergent recently. I had seen parts of it but never sat thru the whole movie.

There was a copy of the book in the room I share at school, so I thought I would compare the book and the movie. The book is better. Then I had to find out what happens next, so I read Insurgent. Stayed up late one night and finished it in 3 days. 

Now I'm reading the 3rd book. It is hard to put down. 

I have other books checked out but can't seem to break away from reading this series.

Have you ever had to keep reading a book? 

Looking forward to finishing but also dreading the end.
