Jay loves to sit in their house by the river and listen to his stories of the Great Spirit and the Earth Mother. But outside, danger is at their door; food is getting scarcer, tribes are at war, and all the time the river water is rising...A brand new and exciting tale, based on real historical and archaeological evidence, this story is full of Terry Deary's imaginative style and dry wit.Book band: Grey_______________'Bubbling with wit, language play and robust dialogue....just the right mix of ingredients to trigger young readers' interest in all things historical' - Books For Keeps
