The Glass Books of the Dream Eaters by GW Dahlquist

Convoluted, long but worthwhile victorian melodrama. Celeste Temple is newly arrived to Victorian or Edwardian London from an unnamed island nation, she attaches herself to the first eligable bachelor of suitable social standing that she meets, but when her fiance Roger breaks off their engagement she is interested to know why. Her curiosity leads her into a world of secrets and mystery, of high end prostitutes with strange marks around their eyes, of sex and sensuality and the mysterious glass books. As dreamy as Kubla Khan with arousing eroticism.
