The Redwallers face some of their most dangerous villains yet in a treacherous hunt for long-lost treasure.

The destinies of the badger lord dubbed Sunflash and his mortal enemy, the ferret warlord Swartt Sixclaw, are entwined with those of many creatures, particularly the inhabitants of Redwall Abbey.

Captured and enslaved by the corsair stoat Badrang, young mouse warrior Martin vows to end the evil beast's plundering and killing.

The mousemaid Mariel achieves victory at sea for the animals of Redwall Abbey, fighting the savage pirate rat Gabool the Wild, warlord of rodent corsairs.

Urthstripe the Strong, a wise old badger, leads the animals of the great fortress of Salamandastron and Redwall Abbey against the weasel Ferahgo the Assassin and his corps of vermin.

Lord Asheye, the Badger Lord of Salamandastron envisions his own demise, prompting him to send a clever haremaid from the Long Patrol on a quest to find his successor. Meanwhile, Gorath, an orphaned warrior badger, has a vision of his own: a sword-wielding mouse tells him to follow a thief to Redwall. Complicating matters are Vizka Longtooth and his scurrilous Sea Raiders who want to capture Redwall for themselves.

Triss, Shogg, and Welfo escape from slavery at Riftgard and are pursued across the sea toward Redwall by Princess Kurdah, Prince Bladd, and a band of freebooters who seek the rumored treasure of Brockhall. Meanwhile, Scarum and Sagax head off to sea with their friend Kroova the otter, looking for adventure, and there is something very scary lurking in the woods around Redwall Abbey.

The murderous and evil Razzid Wearat and his crew of vermin are on a mission to seize Redwall Abbey for themselves, and Abbot Thibb and his Redwallers must defend their home with the help of the hares of the Longpatrol and the Rogue Crew of sea otters.

On his way to invade Redwall Abbey, vicious and tyrannical Captain Vizka Longtooth captures Gorath, the brave young badger whose predicted destiny is to become the next Badger Lord.
