i wish i could read, a really really really thorough damn history of the world.
Try "The Story of Civilization," by Will and Ariel Durant. I didn't reference it as a single book, because it's not, it's eleven books. It is well worth reading however, and is arguably the best "whole earth history" ever written. This man and his wife wanted to write a "biography" of history, and to avoid the cult of the expert specialist. As for accounts which disagree, you'll never get away from that. You have to learn to apply your own judgment.
