Things Not Seen by Andrew Clements
If you're looking for an easy read with lots of twists, this is a great book to add to your list.
One of the classes that I've been helping out in when I sub at Duniway Middle School is a 7th grade Language Arts class. They are reading this title for class, and the teacher recommended it to me. She lent me one of her copies, and I read it all in just a few shorts days. I think I started reading it on Thursday and finished it on Saturday.
This story is quite unique. It's about a 15-year old boy who wakes up one morning and finds himself invisible. The rest of the book is about him and his family trying to make sense of all this--and trying to make it right. He certainly doesn't want to live out the rest of his life like this!! At first this might not seem like a very intriguing book, but Clements add enough surprise elements that it is really a joy to read.
**Side note: If your dreams at night have a tendency to incorporate things you've read or watched, I don't recommend reading this before bedtime. I did, and I had a tough time convincing myself that I had not woken up the next morning invisible. As I laid in bed struggling to come to grips with the fact that it was morning and time to get up, I had to keep looking at my arm to ensure myself that it was, in fact, still visible. :-)
