"Naturally you're out of book space. Everyone is always out of book space. If you're not out of bookspace, you're probably not worth knowing. You are probably still worth knowing but just not as interesting as those running out of space :)
Defending Jacob is by far one of the best books I've read. A GREAT list of books that are impossible to put down! If you want a book that will keep you up reading until WAAAY too late, this list is perfect! Tons of great suggestions.
