A review by eeeeeeee
The Shaker Experience in America: A History of the United Society of Believers by Stephen J. Stein

informative inspiring slow-paced

5.0

Probably the most comprehensive and informative book on the Shakers I've read (and presumably that has been written because I don't think another broad survey has been done since now).  Not a great intro (it's very dense and detailed) but once you want to learn more than the surface level, this is probably the right book to do so.
