I've enjoyed reading this book, both as a general reference to prophecies about the new Revelation and especially for references from the Sunni perspective. If you have friends of Sunni background (about 85% of the Islamic world) this is the best book I've seen for them. They can learn about the Baha'i Faith and its connections to Islamic prophecies without the additional stumbling block of the Shia/Sunni split. The issue is briefly addressed on pgs 324-25, but is set in its proper context i.e. that a whole new Revelation is much more significant than divisions between, or within, the religions of the past.
Many thanks to Mr. Jassat for filling this gap in Baha'i literature!
