The Soul Master is a novel by Graham Dunstan Martin published in 1984.
The Soul Master is a novel in which Kosmion builds an army of puppets under his control by absorbing his victims.
Dave Langford reviewed The Soul Master for White Dwarf #55, and stated that "I admired the ingenuity, but less so the writing: portentousness, reminders of the author's presence ('How shall I put it?' he wonders in print, breaking the narrative spell) and overuse of Significant Understatement."[1]
