Thought you knew about history? Think again. The dinosaurs were not killed off by an asteroid strike, the Koban in their thousands did that. They are still here, and have been throughout history, killing and eating millions. But now there is only one shapeshifting Koban hunter left, and only he and his acid-tongued AI stand in the way of the Koban turning humans into nothing more than cattle. Alterative history with a science fiction twist.
