I read the first book of the Hunger Games last weekend. I'd heard it was supposed to be good, but I was surprised how good. I blew through it in two sittings.
I've never read a book that I thought would translate so well on to the big screen. The plot is solid, but not so complex that it won't fit into two hours. There aren't a bunch of hidden motivations or inner dialogue and there are plenty of great action scenes.
I can't wait!
