This book provides a serviceable overview of the last 3000 years of Chinese history, spending about half its length on the period leading up to the Manchurian Qing dynasty, and the second half examining the development of modern China.
I appreciated how adeptly Roberts dealt with such an enormous amount of history in such a short space - particularly in the first half, which by necessity galloped through the decades at an alarming pace. I often thought in all seriousness than any single sentence could stand as the thesis for a doctoral dissertation.
On the other hand, I often felt that Roberts gave us too many trees and not enough forest, and at times this was frustrating. To take one example, I was genuinely stunned to find the final collapse of the Qing dynasty mentioned only elliptically, and in a complicated paragraph with a lot of details on officials shifting allegiances and so forth. I couldn't believe my eyes - the fall of the dynastic system that had provided the fundamental structure for Chinese society since 221 BCE fell apart after more than two thousand years, and he not only didn't pause to comment on its larger significance, he barely even noted that it happened. I read that section three times convinced I must be missing something, but there it is.
I was also a bit annoyed by Roberts's inflexible use of Pinyin as a transliteration scheme, even when the Wade-Giles equivalents are far better known. As a non-specialist, it actually took me a while to realize that Xianggang refers to what virtually every other English speaker would call Hong Kong, or that Jiang Jieshi is who I think of as Chiang Kai-shek. If you wish to stick to your transcription system, that's fine, but it's worth a parenthetical note on the first instance.
I definitely learned a lot from this book, but I would have preferred Roberts to tell more of a story and put less focus on a barrage of details I'm unlikely to retain.
