The Red Door by Lizbeth Dusseau
A bizarre journey awaits Lily Matisse beyond the red door. A simple flower seller at a street corner stand, she’s lured through this ancient gateway by a mysterious lover, Ravel. While in the midst of making love in his hideaway, she finds herself suddenly disappearing into worlds of sexual deviancy … where there are no taboos, where nothing remains sacred, where men subdue her and she must surrender. A primitive goddess in an orgy on the beach, a bawdy tavern wench serving a brutal master, a slut on trial for treason, and a princess doomed to be the pawn of an evil sorceress … are just some of the astonishing women she becomes on the other side of Ravel's Red Door.
