More than one --
Year of Wonders by Geraldine Brooks (Not a cheery book, but oh so good)
Gap Creek by Robert Morgan
Ender's Game by Orson Scott Card (I think it's being made into a movie)
Swan Song by Robert MacCammon
the end of Mr Y by Scarlett Thomas and Divided Kingdom by thomson
Yeah! oh my god this book was so good it made me cry. a little ****** not my taste but it was a beautiful book. It was called "HOW I LIVE NOW".
You people should read it some time its not a big book or anything like that but you would wish there was a second part. . Sadly there's not.
I liked Robopocalypse...word on the street is that it actually has been made into a movie.
It's like World War Z but with robots instead of zombies.
Twilight Eyes by Dean Koonce, and Duma Key by Stephen King
