"What a fantastic story! Christy and her pals have a huge adventure, while taking us on a whistle stop tour of some of the biggest issues facing us all today – fossil fuels, carbon footprints, food waste, plastics and more. I loved the way Petra has woven a biblical understanding of creation care and some tricky moral dilemmas into the story. Highly recommended for young readers." - Caroline Pomeroy, Climate Scientist and Director of Climate Stewards

"A great way to engage children in real and significant concerns through a fabulous story." - Revd Cate Williams, Environmental Engagement Officer, Diocese of Gloucester

"An exciting story with lots of eco-dilemmas and twists and turns. It’s packed full of amazing facts and ideas of positive changes we can all make. A reminder that we all have a voice and can all make a difference, especially when we work together." - Sarah, mum to Ethan aged 9 and Harriet and Isabelle aged 7

"It's a very fun book, full of surprises. I got into it quickly because the first bit, about the climate march, was very exciting and fun straight away." - Linde, aged 9

"I really like it that, in this book, Christy is the narrator, and that it's also about her friends Amira, Matteo and Sam. (I really enjoyed the first book, Science Geek Sam, too!) Amira is a new character and Matteo is very funny. The story is full of their adventures. I have learned lots of new things about wildlife and science, and about Ecuador. It's a fun and exciting book." - Matthew, aged 11
