Tom Clark and His Wife, Their Double Dreams, and the Curious Things that Befell them Therein; being The Rosicrucian’s Story, Dr. P. B. Randolph. New York: Sinclair Tousey, 1863
This book was bound with The Wonderful Story of Ravalette.
I’ve only read small pieces of it, but given Randolph’s propensities, I’d expect there to be some bits about equality, sexuality, and spirituality. I may be wrong, however, so I’ll adjust this post as I find out (or you can leave comments, if you’ve read the story).
