Keith Brooke studied environmental science at university, and took a year out after graduating to write a novel. That novel, Keepers of the Peace, was published by Gollancz in 1990. He remained a full-time writer for some eight years, but now works part-time for the University of Essex.

Brooke's first story was published in the British small press magazine Dream in 1989, but it was his first sale to Interzone, the story 'Adenotropic Man', which first brought him notice. He continued to be published in Interzone throughout the 1990s. There was, however, a nine-year gap between his third novel, Expatria Incorporated, and his fourth, Lord of Stone (although the latter was originally published on-line in 1997). In 2001 and 2002, US-based Cosmos Books published Brooke's three novels from the early 1990s in their first US editions. 2006 saw publication of Genetopia, achieving publisher Pyr's first ever starred review in Publishers Weekly. His 2009 novel The Accord picked up a second starred PW review.

In August 1997, Brooke founded the Infinity Plus website, publishing original and reprinted science fiction book reviews and stories. He continued regular updates for the next ten years, all of which appeared for free. Brooke invited hundreds of SF authors to showcase their work, beginning with several well-known British authors but eventually including newer authors and many from other countries. Regular updates ceased in August 2007, although the archive is still available.

Brooke also publishes teen fiction under the pen-name Nick Gifford, with four novels published by Puffin between 2003 and 2006.
