I predominantly read this book to see why my nephew loves the series so much. He told me that it doesn't really matter which order you read the books in, so I picked up one of the ones I had at work to try.
I have read the very first Beast Quest book, but this was one of the other mini series within the whole. I can definitely see why they appeal to children. An excellent introduction to adventure chapter books, and for me preferable to the Daisy Meadows Rainbow Fairies which are aimed at a similar age.
Tom and Eleanor show some excellent team work in defeating the monster and pirates in this quest/adventure.
