From the publisher:
There has never been a Redwall hero quite like Rakkety Tam, the roguish Highlander squirrel who sets off for Mossflower Wood on a mercenary errand and loses his heart to the charms of Redwall Abbey. And there's never been a villain quite like Gulo the Savage: a vicious beast-eating wolverine who descends upon the Abbey in search of a relic called the Walking Stone. Readers will cheer at the return of the Long Patrol, the antics of a renegade vole thief, and the emergence of a new champion to wield the sword of Martin.
