Head Games

Blurb

Head Games is an original novel written by Steve Lyons and based on the long-running British science fiction television series Doctor Who. It features the Seventh Doctor, Bernice, Chris, Roz, Mel and Ace.
Head Games is a sequel to Lyons' earlier New Adventure Conundrum, and again features the Land of Fiction first seen the 1968 serial The Mind Robber.
Head Games continues a theme running through the New Adventures starting from Timewyrm: Revelation in which the Doctor becomes Time's Champion, and that previous incarnations still in some sense exist within his mind. This novel suggests that the Seventh Doctor was somehow able to terminate the life of his previous incarnation on Lakertya in order to become Time's Champion. This in turn caused the Sixth Doctor to eventually turn into the Valeyard — the evil version of the Doctor seen in the serial The Trial of a Time Lord.
