If you want to know all about how Buddhism spread from its origin; this is the book for you. On the other hand, if your looking for a book that explains basic buddhist belief and practice... Look else where. Breif descriptions of karma and selflessness, Extensive detail of where the dharma spred to. So for beginners like myself, I would pass on this one.
