Indigo, bookseller & CP-loving submissive, is obsessed with an antiquarian work of sadomasochism which eluded her father all his life. Caned, roped & shamed through the fleshpots of Europe, she will suffer any indignity to prevent Dervil Badon & his transsexual slave Natasha from getting their hands on her prize. But Dervil has no intention of allowing a mere submissive to own the legendary Book of Punishment.
