As in... The Host, by Stephanie Meyer (of Twilight fame).
I recently devoured this 600+ page book. In a week. I did nothing but read when I was home. I got the majority of it done one weekend. I laid on the couch and read read read read. Reading is my first choice activity. I read every night. It's one of the reasons I am so passionate about teaching my students to read and why I am/was thrilled beyond belief when my son started reading at age 3. I'm glad I got it done before the movie came out!
