Exit to Eden
Anne Rice initially published Exit to Eden under the pen name Anne Rampling in 1985. In it, Lisa Kelly is the founder of a BDSM resort, The Club, where visitors can play master or mistress and nothing is forbidden. Elliot, a photojournalist, shows up, and together they explore their dark sides and fall in love. The book was made into a movie by Garry Marshall and, not surprisingly, drastically changed.
