Can you guys recommend a good photobook/collection to me?

I just looked through the national geographic's collection of the best photos of 2011 and was blown away. I got some amazon money for x-mas and wanna get a good book filled with awesome photos, maybe like a compilation, not necessarily from only one photographer but I'm also interested in that as well. I really like wildlife, portraits, cityscapes n architecture.. I mean basically everything, which makes it a bit hard to recommend a certain book but I'll be interested in everything. Thanks a lot
