The Book of Priceless Substance

An exciting erotic thriller about what we are willing to do to get what we need… and what we want. After a tragedy that turned her life upside down, former writer Lily Albrecht resigned herself to a dull, colorless existence as a rare book dealer. Until she received an offer to find a book that could fix everything… The “Book of Priceless Substance” – a guide to 17th-century sexual magic, promising unlimited power and unparalleled sexual pleasure. If the rumors are to be believed, it is the most powerful occult book in the world, and some of the wealthy are willing to pay a fortune to possess it… If only it isn't just an ancient legend. But will Lily be able to fulfill her own desires? Or will she lose everything in the pursuit of a mirage? ___________________________________________ "Sara Gren's prose, like the sought-after grimoire, is palpably seductive.

Gren's writing is incredibly enticing - just like Lily Albrecht, readers have no choice but to follow the book to its sinister conclusion." - New York Times "Sara Gren's book is a mix of a buyer's mystery, erotica, and a pinch of existential horror. And it's all magnificent." - Paul Tremblay, bestselling author of "A Cabin at the End of the World" "Extravagant, sexual, and irresistible. I loved it." - Lauren Bukes
