Parasite is an original novel written by Jim Mortimore and based on the long-running British science fiction television series Doctor Who. It features the Seventh Doctor, Ace and Bernice. A prelude to the novel, also penned by Mortimore, appeared in Doctor Who Magazine #220.
As with all Doctor Who spin-off media, its relationship to the televised serials is open to interpretation.
