The Crooked World is a BBC Books original novel written by Steve Lyons and based on the long-running British science fiction television series Doctor Who.

[1] It features the Eighth Doctor, Fitz and Anji.

The Doctor accidentally brings the concept of reality to a world based on cartoon physics.

In Interzone, Matt Hills writes, "Lyon's tenth Who novel seems at first as if it is going to be a very long set of tiresome in-jokes and references.

But it opens out into a sharply drawn meditation on social justice and individual guilt, as well as dealing with the cultural transmission of ideas.
