The full title of this book is- The Mongol art of war, by Timothy May,published by pen and sword,hardback and has just over 200 pages and costs around £20. I got mine from Amazon new for just under twelve pounds including postage.
The book starts of with a brief account of the rise of the Mongol power. The way the Mongols gathered and organised their armies is covered next. Training and weapons are covered as are logistics etc. Tactics are I thought very well described as is grand strategy. You are given a understanding of how wide ranging a Mongol attack could be. Opponents are but briefly covered which is understandable given the topic of the book. I was glad so see a more that usually given bit of space given to Chinese etc units in Mongolian service. Brief accounts of some key battle are also given.
Ultimately this is a good book. I would have liked to have seen more on the later Mongol armies but that's a small complaint.
