Summary
The protagonist, Mariel Gullwhacker, was enslaved by Gabool the Wild when her father Joseph's ship, the Periwinkle, was captured. It had been carrying a bell to Lord Rawnblade Widestripe in Salamandastron, and that, too, was seized by Gabool. After attempting to attack Gabool, the mouse was thrown into the sea and washed up on the shore, with no memory. She took the name "Storm Gullwhacker", and gave the name "Gullwhacker" to the rope she had used to fight off a seabird.

Three members of the Long Patrol, Colonel Clary, Brigadier Thyme, and the Honorable Rosemary, escorted her to Redwall Abbey, where woodlanders helped her regain her memory. She befriended a mouse named Dandin, the hedgehog Durry Quill, and musical hare Tarquin Longleap Woodsorrel, and they journeyed to Gabool's island of Terramort to defeat him. (Lord Rawnblade also joined with the four comrades.) The denizens of Redwall, meanwhile, defended the Abbey against Greypatch, a searat on the run from Gabool's army, and his horde. Clary and Thyme, along with their secretive squirrel friend Pakatugg, were killed freeing slaves from Greypatch's camp.
