The Invisibles (1994), Volume 1

Throughout history, a secret society called the Invisibles, who count among their number Lord Byron and Percy Shelley, work against the forces of order that seek to repress humanity's growth. In this first collection, the Invisibles' latest recruit, a teenage lout from the streets of London, must survive a bizarre, mind-altering training course before being projected into the past to help enlist the Marquis de Sade.
