Aria and the Kumara God

In this exciting return to the world of the Astromancer, will Ariā manage to make the impossible climb up to the stars and free Te Kōkōrangi from Ruatapu's clutches before time runs out?

The future is looking bleak: not only is the Astromancer held captive by the wicked Ruatapu, but also the kūmara crops are dying.
Ariā and her fellow apprentices — and Kurī — must repeat Tāwhaki’s great feat and climb up into the heavens to ask the star Whānui for help.
They have to act quickly because Matariki is drawing close, but the journey seems impossible . . .

Also translated into te reo Māori as A Ariā me te Atua o te Kūmara.
