The Greek Passion by Nikos Kazantzakis (I think it's better than Zorba, The Greek)

The Annotated Alice (Alice's Adventures in Wonderland and Through the Looking Glass) by Lewis Carroll with annotations by Martin Gardner

At Swim Two Birds by Flann O'Brien (by a writer, for writers, about creativity and the creative process...one of the most interesting and frustrating books...I'm still reading it and know I will have to read it again one day)

Essays of E. B. White by E. B. White

Me Talk Pretty One Day by David Sedaris

Wicked: The Life and Times of the Wicked Witch of the West by Gregory Maguire (a far more incredible story than that Broadway musical can convey)
