This is the second in a four-volume series surveying the writings of Baha'u'llah. Volume II, covering the period of Baha'u'llah's successive exiles to Constantinople and Adrianople, includes among many other items the Tablet of Ahmad and the Tablets to the Kings. There are many quotations from contemporary records and memoirs, in translation for the first time, and a number of relevant photographs.
The Revelation of Baha’u’llah
This is one of the best books I have ever read. All 4 volumes in this series are incredible. They are educational, informative, interesting, and inspiring. Highly recommend reading all of them.
