"A Supposedly Fun Thing I'll Never Do Again" by David Foster Wallace, pretty sure this book has changed how a generation writes. At least it convinced a generation they'll never be as good as DFW.

"Norwegian Wood" by Haruki Murakami, which I like to think of as a Japanese C.i.t.R.

G.E.B. - power through it, soldier!

"Making Certain it Goes On", by Richard Hugo. An instructional book on how to write poetry, or to basically do just about anything. I highly recommend it to all programmers.
