Triss is a brave squirrelmaid, enslaved by the evil ferret King Agarnu and his daughter, Princess Kurda. Along with Shogg the otter and Welfo the hedgehog, she plans a daring escape by sea.

In her flights, Triss happens upon Redwall, where the abbey creatures discover a new hero in her. Someone bold enough to carry the sword of Martin and confront the evil that threatens them.

This tale is filled with scrumptious feasts, rollicking humor, swashbuckling heroes, faithful friends, and treacherous villains. These elements magically combine through three intertwined action-packed plots into one unforgettable, spellbinding story.
