All these books you're recommending - and my library doesn't have any of them.
On my list is the rest of the Ender's Game series - I've read the first two now and am waiting for the third to come back to the library. Excellent books. I've also been meaning to try out Terry Pratchett - I keep forgetting.
It seems like there should be more... *frowns at memory* I've hit several of them this summer - "This Present Darkness" by Frank Peretti and "Watership Down" are the two that come to mind (both thoroughly enjoyed). My next set of books will probably come from the books people have listed here.
