“Planet Protectors” was too young for my 13 year old, so my friend read it with her primary aged children. They read it as a family and enjoyed discussing the questions and writing ideas at the end of each chapter.
It opened up some good discussions and got both children and adults thinking about things they could change! They liked that it was written by a Christian and had a focus on looking after God’s creation, but noted that it would be a good book for those without a faith too.
