The Collectible Andy Weir
I know he only has one book, but he seems to be a popular author here amongst those that have read The Martian and there are two (that I know of) collectible editions of the book and a movie due out this fall. With that said, here's my Andy Weir collection so far. I also have a lettered and limited edition on preorder from SP; will add pictures of those when the eventually arrive.
