Reviews

Arthur is my favourite character because he has to fight 7 trustees to get 7 keys to the kingdom. This book he challenges Drowned Wednesday. I would recommend this book.

In this book Arthur meets the sailors. I like this one because Arthur is out of his comfort zone and so has no idea what to do until he meets sunscorch.
