American Yesterday - Eric Sloane
Written in the early 50s and all accounts of Sloanes great grandfather. How people lived, how the architecture was done, how towns were arranged. Short and not the most well written but gives a good bit of insight to our past.
Starving Jesus - Craig Gross and JR Mahon
You might be surprised if you pick this up. Both authors write it but unlike most co-written books both of their thoughts on topics are there; on in black ink, one in red. They tackle the hypocrisy of "Christians" today, make very good points, and basically call people out for being idiots. Very well written. These are the guys that got kicked out of their church (both were pastors) for starting http://www.xxxchurch.com.
