The Book of The Most Precious Substance

Highly anticipated new work from Sarah Gran, author of the Claire DeWitt series. Publication set for Feb 2022.

After a tragedy too painful to bear, former novelist Lily Albrecht has resigned herself to a dull, sexless life as a rare book dealer. Until she gets a lead on a book that just might turn everything around. The Book of the Most Precious Substance is a 17th century manual on sex magic, rumored to be the most powerful occult book ever written.
