The number is indeed somewhat intimidating. However, most of the books are stand-alone adventures. Only two of them are direct sequels. (Mattimeo is a sequel to Redwall and The Bellmaker to Mariel of Redwall.) Often many years pass between books, so that characters who are youngsters in one book may be old in other books. The most recent books have even larger gaps between them. Triss is set six generations after The Taggerung. Books after that change the cast completely without even informing us how much time has passed between.

Anyway, to keep a long story short: it's not one continuous storyline, just many books taking place in the same world.
