Also, World War Z is my favorite zombie book. I haven't seen the movie but it seems that they took out enough of what I liked about the book to make me not interested.
I subscribe to that suggestion. World War Z is a great book. Also, avoid the movie. Other than the title, it has nothing of the book. NOTHING... I mean, they didn't even keep the zombies.
Other than that, someone already mentioned House of Leaves... Awesome book. Highly experimental, the kind of book that can mess with your head...
In Science Fiction, I would like to add Childhood's End, of Clarke. In Fantasy, the Song of Ice and Fire series is popular at the moment, and they are pretty good books on their own right.
