These are the ones I've liked best
Neal Thompson - "Driving with the Devil: Southern Moonshine, Detroit Wheels, and the Birth of NASCAR"
Dee Brown - "Bury My Heart at Wounded Knee"
Nicholas Johnson - "Big Dead Place" - about living in Antartica
Mark Noll - "The Civil War as a Theological Crisis"
David Halberstam - "The Coldest Winter: America and the Korean War"
Stanley Karnnow - "In Our Image: America's Empire in the Philippines"
Esmerelda Santiago - "When I was Puerto Rican"
Lara Pawson - "In the Name of the People" (about Angola)
Marc Benioff - "Behind the Cloud" (surprisingly good for a business book)
Keith Anderson - "The Digital Cathedral" (book a friend of mine wrote, hard to describe, but suprised me at how good it is)
Adam Hochschild - "King Leopold's Ghost" (how the Congo became a colony)
Jessica Livingston - "Founders at Work"
"The Singapore Story: The memoirs of Lee Kuan Yew" (a little dry / long at points, but otherwise very instructive)
"Listening spirituality, Vol. 1: Personal Spiritual Practices Among Friends" (a book about Quakerism that was surprisingly good)
Michael Fogus - "Functional Javascript"
David Shi - "The Simple Life: Plain Living and High Thinking in American Culture" (traces the historical movements in the U.S. that value "simplicity" as a virtue, this was an interesting way to look at history)
A.J. Swoboda and studies, "Blood Cries Out" (recommended to me by someone I know who is in seminary, this is Pentacostal theologians writing about ecology)
Frank Moraes - "The Importance of Being Black" (an Indian journalist in the 60s who took a tour of Africa and wrote a book; his books are hard to find though)
