I bought this book used, on vacation to the UK, looking for a good general history of Eastern Europe in preparation for a trip there this fall. The books style is unique, and it took me a while to get through it, but it's very interesting and overall a great introduction.
Firstly, it's worth noting that the author has a very relaxed and humorous style, which makes even dry sections very interesting. He also includes a huge number of "trivial" asides - little stories that I always found entertaining, even if I probably won't retain many of them.
The book is organized chronologically first, then - after a summary introduction of the time period in question - by country or region. Depending upon the geopolitical structure of the particular time period, the regional breakdown varies. Then there is often a special topic ("The Germans", "The Jews", "The Gypsies",...) to close the chapter. It's a good way to cover a broad topic, even if it means that the reader doesn't get chronological coverage start-to-finish of ANY specific location.
The chronological chapters cover time periods of varying length ... 300-400 years each at the beginning, tightening up towards the modern era (WW II gets its own chapter, and so does the Cold War). I like this approach, I just found that it made it difficult to read for long stretches at a time, because it makes for a choppy, non-narrative structure. I took months to finish (not my only book during this time, but that's still a long time for me for a 500-ish page book).
The author is not particularly "politically correct" (as mentioned above, there's a sub-chapter named "The Gypsies" !), which is refreshing. Nor is he preachy or judgmental - also refreshing, and making a history of this contentious region with all of its ethnic conflict much more readable. He included plenty of maps - at one point I probably had six bookmarks noting various oft-referenced maps - which is GREAT! He also did something unique and useful: every proper name has a pronunciation key for English speakers, in an obvious format that doesn't require expertise in the IPA system or other esoteric representations.
I did notice a few editorial oversights (misspellings, grammatical errors, etc), but nothing excessive. The only reason I didn't give 5 stars is just because the overall structure, however useful, also has downsides.
