In view of some of the subjects covered at NI Summer School this year, the emphasis once again being placed on the World Order letters of Shoghi Effendi, and general public (and Bahá'í) interest in this whole area, this book is well worth reading. It is a series of papers dealing with aspects of the coming together of the world as a coherent whole—something for which we are all striving and which sometimes seems a long way off. Many questions will be answered and because it is a compilation readers can go straight for the themes that interest them most before moving on to the others. This book is highly recommended for anyone who is interested in the subject—as presumably we all are—but particularly those involved through membership or discussion with organisations of social change.
