Mathematician Stewart and biologist Cohen continue to explore the depths of the Disc with Sir Terry in this mind-mangling combination of fiction, cutting-edge science and philosophy.

Marjorie Daw is a librarian, and takes her job - and indeed the truth of words - very seriously. She doesn't know it, but her world and ours - Roundworld - is in big trouble.
