In the stunning tradition of Watership Down comes a magnificent tale of treachery, destiny, courage and sacrifice -- from the author of Redwall, Mossflower, and Mattimeo.

Dire peril awaits the innocent mousechild Mariel on a voyage with her father across tempest-tossed waters. For Gabool the Wild, King of the Searats, greedily eyes their unsuspecting vessel -- hungry for plunder . . . and destruction. Mercilessly cast overboard by the evil rodent, Mariel is washed ashore near Redwall Abbey barely alive . . . with no memory. But with the aid of a small yet hardy band of Woodlanders, the courageous mousemaid is determined to reclaim her identity . . . and to enact a rightful vengeance on the bloodthirsty pirate and his terrible minions.
