Poker Books

[imitation]

I want to ask this here as it's where i've heard the books mentioned in past. But I haven't bought any poker material since SSHE was released, I'm sure people have been talking about another book, King Yao's is it, which is quite good? Also anything else I should add to the list, I'm buying a bunch of investing / stock market type books to see if it's something i'm interested in so I figured i'd lump in some poker books with the order. I'm also getting the harrington NL tourney stuff but what else do you guys think I might have missed?

Cheers.
