Firstly the positives : The book is extremely well written and readable. The early sections of the book represent a very good introduction to the fundamentals of Buddhism and its purpose. There are some real gems of insight which do encourage the reader to re-think their cultural baggage and in-built perceptions. Finally, it is of course a wonderful gesture for the author to make this work available for free as part of the mission to spread the ideals of Buddhism.
Secondly the negatives : Unlike previous reviewers, I found sections of the book tedious to read and very repetitious. My biggest criticism however is that some sweeping statements of generalisation, never proven but stated as given, underpin much of the philosophy of the second part of the book. Never having been convinced of the premises on which those aspects of the philosophy are built, not surprisingly I found it hard to take on board those philosophical conclusions themselves.
In summary, well worth a read but not without shortcomings.
