After conquering the Candlestone, Billy Bannister and Bonnie Silver travel to England, called to complete a dangerous assignment that only the rightful heir to King Arthur's throne can accomplish.
I do not recommend this book or any of the others for children 10 or under because though it isn't inappropriate, it has scary parts unsuitable for the ages I mentioned. I love it, but children the age I mentioned couldn't handle it. But, it is a WONDERFUL book, and if 10 year olds wanted to try it, I would POSSIBLY let them hear it. But just don't go any further.
