As the family member of an SGI-UK member, I found this book very interesting. I would recommend it to anyone who wants to know more about the Soka Gakkai International movement in UK (or the SGI in general) and about Nichiren Daishonin's Buddhism.
This book gives the reader a surface view of SGI in the UK but the leaves out any in-depth analysis. For this reason I found this book quite disappointing. It seems the authors did not want to take sides and just produced something that is quite flat and bland. Some comparisons of SGI UK and other movements such as Scientology were useful but too short. Moreover, for people not familiar with the terminology of the SGI UK movement this book may be hard to follow.
