In this 60s retro prequel to the bizarro-noir Bloodsuckers Handbook (AKA Enchiridion), Bloodsuckers Planet follows the crew of the space ship Argosy as they respond to a distress signal from the industrial Planet Mara only to discover the planet is ruled by the sinister Mother Vampire. Along the way, they encounter disease-carrying Mara bats, a talking space roach, and Adrianna, the gynoid whose developing self-awareness is aided by her collection of vintage romance comics.
