Huge, green, and scaly, alien Professor J’o’ Ka Joarchim can’t convince the local peasants that he’s not a man-eating monster. The villagers chain a young woman to a cliff in sacrifice to him, but she has her own ideas about that. Helping her escape only aggravates the situation, and J'o' ends up with a collection of luckless human victims, all increasingly dependent on him for their survival.
Meanwhile, J'o' must keep his new pets a secret, since interfering in human society is a serious violation of Inter-dimensional Law. The longer he stays on Earth, the more trouble awaits him back home.
THEY CALLED ME DRAGON is the story of a feisty young heroine, an assortment of outcasts, and one very confused alien as they conquer the Dark Ages and become legends in the process.
