Kaimanawa Princess
It's about a girl named Becky and she gets a Kaimanawa Pony named Kaimanawa Princess. Becky and some other people have a debate about if the Kaimanawa Ponies should be killed or not.
By the way the Kaimanawa Ponies are New Zealand's Wild Pony and they live in the Kaimanawa Ranges which are in New Zealand.
"Kaimanawa" means "wind-eater" in Maori.
