The Highest Science

Blurb

The Highest Science is an original novel written by Gareth Roberts and based on the long-running British science fiction television series Doctor Who. It features the Seventh Doctor and Bernice and the first appearance of the recurring monsters, the Chelonians. A prelude to the novel, also penned by Roberts, appeared in Doctor Who Magazine #196.
The novel was going to be adapted into the 2009 Doctor Who Easter special, making this story, like Human Nature, an early "version" of a canonical television story; the concept was continually altered, however, resulting in "Planet of the Dead". The Chelonians were mentioned onscreen in the episode "The Pandorica Opens" as one of the Doctor's enemy species who have banded together to defeat him, suggesting that the events of the novel have in fact happened.
