My son waits at the school bus stop with his head in this book: he cant put it down. It is a highly imaginative, action-packed adventure story of goodies overcoming baddies in their desire to protect and preserve weird, endangered beasts. I am reading it to my sons aged 6, 8 and 10 and they all try to guess what is going to happen next. It has great momentum, quirky characters and timely humour just when things are getting a bit tense. This is the fourth we have read in this series and I would recommend them to any young readers who have a sense of adventure!
