I just finished Irrisistable(?) Revolution by Shane Claiborne. It was excellent, I definitely recommend it.
Currently I'm reading Eat, Pray, Love by Elizabeth Gilbert. Not necessarily coming from a Christian view point, but she's got some funny stories and interesting insight from her travels.
I'm also reading A Long Way Gone - Memoirs of a boy soldier by Ishmael Beah. I've had this one on the go for a while, though. Its very moving.
