I'm currently rereading Contact, by Carl Sagan, which is my favorite book ever.
After that, I have three books to read and analyze over the next couple months as part of my summer homework for my AP English class next school year.
They are:
A Separate Peace by John Knowles
Into the Wild by Jon Krakauer
The Secret History by Donna Tartt
Everyone who's in that class with me is whining about actually having to do something over the summer; I guess they wanted easy classes for their senior year. I personally love analyzing literature.
