A prehistoric survival adventure about a boy and a horse who rescue one another, from the Carnegie Medal-winning author of Apache and Buffalo Soldier.

"A boy without a clan was nothing. No one. A boy without a clan was easy prey."
Oak, son of the Deer clan chief, hopes that this summer he will finally be allowed to join the hunt and make his father proud of him. But this year is not like other years – the rains have failed, his father has fallen out with the Bear chief, and everyone is mistrustful of the new creatures that have been spotted near their encampment: horses. Then Oak becomes separated from his clan with only a young horse for company, and it seems that surely the worst has happened. But perhaps not all animals are prey. Perhaps Horse can be clan too.
