Summer Reading

It's hard to imagine, but in 6 weeks I am finished with formal education - at least for a season.
Which means, I can read whatever I want. About this time every year I make a list of books of all types
(theology, philosophy, spiritual formation, dissertations on the politics of Jesus, biography, leadership,
fiction, poetry, history, etc). Here is where I need your help. If anybody still reads this, I would like you
to give me of few of your "must reads." I need to start building my Amazon "wishlist." As of now, it has
one item:

"The Politics of Jesus" - John Howard Yoder

What else would you add?
