This kids book is kinda famous where I live. It‘s a fantasy about monsters who live under mountains around Auckland, all of which are extinct volcanoes. I haven‘t read it but I saw the mini series back in the 80s.
The other two pictures are of my rock. (Not actually mine of course!) This is Rangitoto, a volcano I live in the shadow of, taonga (treasure) of Ngāi Tai and Aucklanders.
