In related news, Marlfox was one of the books I remember most strongly from growing up.

Interestingly, it reintroduces Noonvale (supposed to be kept secret after the events of "Martin the Warrior"), and the Hidden Lake and its island (found by our first squirrel Redwall Warrior and Alma in "Salamandastron," I believe), though there was no sign of a castle then, just a "ghost badger" (Urthwyte) and his caretakers.

Oh, and apparently the entire tapestry gets stolen this time. Cluny the Scourge really gets shown up yet again, doesn't he?
