"Children are very much part of a family's decision to buy a pet and armed with the right knowledge, they could influence ethical choices and eventually maybe put puppy farms out of business."
Viola Vincent, an anagram of Catlin V Nove, is the pen name Caitlin uses to disguise her secret identity as a rookie reporter for the local paper.
From the moment the teen encounters sick and emaciated Sissy at the local vet clinic, the pair's destinies become entwined in a compelling and touching story.
"Puppy farms, sometimes called puppy mills or puppy factories, can be found all over the world.
"This is a flourishing global industry fuelled by online trading sites and our 'must have' consumer culture. Celebrities posting selfies with their petite pooches don't help."
Anna said the book, written for 10 to 13 year olds, is based on extensive research, including hours spent watching undercover video footage of filthy and inhumane conditions inside puppy farms.
"I've learnt more about this business than I really wanted to but the message of the book is optimistic and hopefully empowering for young readers."
Through Underdog, young readers will take away the message that their voice matters.
"Don't be afraid to use it and if you care enough, take action and bring about change.
There are lots of kids out there who really care about what's going on in the world.
"I hope my books contribute to their knowledge and demonstrate the transformational power of good journalism."
- The official launch of Underdog is taking place at Paraparaumu Library's meeting room tomorrow evening, Thursday, November 23, from 7pm.
