Query: First off I'll admit...

I didn't read this book from cover to cover, but mainly dipped into the latter part, from which I learned about events such as the Mongol invasion of Java of which I was unaware, as well as learning more about the Mongol invasion of Japan than I had known before. I am not particularly a student of Genghis Khan and the Mongal conquests, but do feel reasonably well informed on events up to 1260. Thus the material concerning events after 1260 was what I was interested in, and I feel the book did a fine, informative job on that. So for me the book was excellent, and I give it 5 stars on that basis.
