ROD DUNCAN writes alternate history, fantasy and contemporary crime. His novels have been shortlisted for the Philip K Dick Award, the East Midlands Book Award and the John Creasey Dagger of the Crime Writers’ Association. A dyslexic with a background in scientific research, he now lectures in creative writing at DeMontfort University. Some might say that he is obsessed with boundary markers, naive 18th Century gravestones and forming friendships with crows. But he says he is interested in the way things change.
