Welsh-born UK chemist, teacher and author who has published sf and fantasy novels under his own name and as Christopher Carpenter, Nathan Elliott, Robert Knight and John Lyon, and some non-genre fiction as by Evan Christie and Alwyn Davies.
Evans won the BSFA award for the 1993 novel Aztec Century, which Iain M. Banks described as 'intelligent, finely written, and towards the end, absolutely nail-biting.'
In addition to his works for younger readers, he wrote the tie-in novelisation of the film Innerspace (1987).
