Olly Hills is an animal lover, cicada expert and one of New Zealand's youngest published authors.
Olly was just 10 years old when he wrote Cicadas of New Zealand, a field guide on 42 different native New Zealand cicadas. It's the first and only field guide book on cicadas in the country, and it came about because of a conversation.
"I was in the car with Mum. We had just been discussing about a few road trips we might do to find some cicadas … it started off as a joke, a conversation about how we should totally write a book about cicadas.
"That then turned into reality roughly five minutes later when she sat me down on a computer and said, 'let's start writing'."
That was two years ago. Since then Olly has sold over 700 books, appeared on TV shows and given a TEDx Talk on his love of cicadas.
