A dark force is rampaging through the forests of Mossflower. Gulo the Savage, wolverine, flesh-eater and brutal killer, has come across the seas in search of his brother, Askor. Askor stole the famous walking stone that will make one of them king of the lands of ice and snow - and Gulo wants it back. Any beast who gets in Gulo's way is dead meat. Literally. Rakkety Tam McBurl is a brave border warrior, travelled south in search of adventure. But when his army is attacked by Gulo's flesh-eating band, adventure finds him. Gulo is heading for the ancient Redwall Abbey - and Rakkety Tam is determined not to let the savage Gulo destroy the peaceful ways of Redwall.
