This is an absolute corker - the best Astrosaurs book in my opinion. Not as long as it looks - there's an Astrosaurs Academy tucked in the back which is great if you haven't read it, slightly disappointing if you have. But Earth Attack is fab
This series of books is brilliant. I have an autistic grandson who really loves to listen to the stories. I think he must have most of the titles to date and plagues our life if he sees another new one.
