This book in the Redwall series stood out as unique from the others in that it was more like a separate story with mainly new characters.  Martin the Warrior was present in the plot but many new characters were introduced.  The main character in the Redwall books are typically quite well-developed.  However, in this book, that was not so much the case.  It was an entertaining and exciting story as usual which earns a recommendation for adding to a school library collection.
