The Enemy Within (Warhammer Novels)
"Richard Lee Byers has written over twenty novels, and countless short stories. A lifelong fantasy, science fiction and horror fan, he began his full time writing career in 1987 after working in the mental health field (he holds an M.A. in psychology) for many years. A resident of the Tampa Bay area, Richard spends much of his leisure time fencing foil, epee and sabre."
