All Ye Lands
I've had a chance to skim the book briefly and read the chapters on the Greeks and on the Aztecs and found them helpful and enlightening. There is a distinct effort to be fair to our Catholic legacy without whitewashing faults. (e.g. I noticed that Charlemagne is treated very favorably with the exception of one paragraph that honestly and without sensationalism explains a terrible thing he did in killing a large group of people who refused to be baptized. It also clears up the false rumors regarding the "evils" of Spain while still criticizing where there is fault).
