A dark force is rampaging through the forests of Mossflower. Gulo the Savage, a 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. Anybeast 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.

The third addition to the beloved Redwall series takes place during the summer of the Golden Plain. Preparation for a great feast are underway at Redwall Abbey, and the young mouse Mattimeo is contributing his share of the labors.

But Mattimeo is the son of Matthias, the guardian of Redwall Abbey, and it is this fact that makes him the target of a fiendish kidnapping plot contrived by the vicious fox, Slagar the Cruel.

When Matthias and his brave followers abandon their homes and face enslavement for the return of their children, the captive Mattimeo stands to prove his worth—and an unexpected hero is born.
