I've read a couple, just finished The Road a few months back. Any suggestions for Post-apocalyptic books or series of book, mostly like Fallout or something of that nature.

For nuclear aftermath, nothing trumps A Canticle For Leibowitz by Walter M. Miller, Jr.
Different apocalyptic subset, but Oryx & Crake by Margaret Atwood is also phenomenal.
Not necessarily all that similar in nature to the Fallout games (which establish a tone rather difficult to capture in novel format), but definitely post-apocalyptic stories worth reading.

The Deathlands series is decent and extensive. There's almost a hundred books. If you've got a used bookstore near you, that would probably be the way to go.

"Deus Irae" by Roger Zelazny is an AWESOME post-apoc book.

I Am Legend by Richard Matheson.
Post-apocalyptic setting, with zombies/vampires hybrids!

Try David Brin's The Postman.
Politically and philosophically interesting, artfully written, and it even has big evil mutants!
Which should tell anybody who's seen the movie that the film was incredibly poorly adapted. -_-

Note: Much of the same goes for "I Am Legend." Actually, I suspect the best film adaptation of that was "The Last Man On Earth," which at least made me want to read the novella. (The best adaptation in any medium is almost certainly the comic, which has the potentially negative aspect of being barely adapted at all. Nearly word for word.)

You might also check out Parable of the Sower by Octavia E. Butler. There is a sequel also but I have not read it.

I highly recommend Wastelands[i][/i] edited by John Joseph Adams. It is a collection of short stories including some by Stephen King, Orson Scott Card, and George R.R. Martin.

The road. Much better in book format than in film.

What about "Metro 2033"?
I got it, and it's really great. Even after having played the game first.

You want to know the real kick in the teeth? The movie wasn't supposed to be such a departure, they made it that way because people didn't like how they did it. Do a google search for "I am legend alternate ending" and marvel at what might have been.

I do want to read Metro 2033, sadly the only language you can get it on a kindle for is German.

I did read about the alternate (Or 'normal', rather) ending, certainly made me question the validity of test audiences. They really shouldn't have changed it.

Summed up pretty well in the first entry on here; http://www.cracked.com/article_16258_5-awesome-movies-ruined-by-last-minute-changes.html

I'm seconding the Metro 2033 recommendation. It is on the Amazon UK kindle store, so I don't how you missed it. Just buy it from a web-browser and then manually transfer it to your kindle. I

Best of all the book is dirt cheap :P

Well, that makes it all the more obnoxious. There isn't even the option to get it in English on the American page. . .

I rather enjoyed 'Cell' by Stephen King. I'm not generally a fan of his work, and I don't know if you're counting zombies as post-apocolyptic... but it's totally unlike his other books (that I've read) and I found it to be a real page-turner. Totally unexpected and a really unique approach to the otherwise rather tired 'zombie formula'.
