Exit to Eden
From BDSM Wiki
Exit to Eden is a novel by Anne Rice, initially published in 1985 under the pen name Anne Rampling, but subsequently under Rice's name.
The novel explores the subject of BDSM in romance novel form. The novel also brought attention to Rice's published works that differed from the type of writing she was better known for (e.g. Interview with the Vampire), such as her Sleeping Beauty series under yet another pen name.
