Nga Waituhi o Rehua

This science fantasy novel in te reo Maori follows four teenagers living on Rehua, a planet settled after Earth is destroyed by ecological disasters and global war. The four raise hokio, giant mystical birds, which take them on flights to explore their new world. On one flight, they discover an island with another colony of people, and here, they are given a quest to interpret hieroglyphic messages drawn on cave walls. Deciphering these symbols leads them to appease the feared tipua wheke, a gargantuan octopus, and help the Turehu, fair-skinned sea fairies, who have discovered a way to return to Earth.
