Urchin and the Rage Tide

For fans of Redwall and other animal fantasy, I highly recommend M.I. McAllister's series The Mistmantle Chronicles. The series focuses on Urchin, a foundling squirrel with strange coloring, but he quickly learns that it's what you go on doing that counts.
Unfortunitely, Urchin and the Rage Tide seems to be the last book of the series. Without giving away spoilers, I will say that McAllister takes what could be a cliched ending and twists ones heart at the fate of characters we've come to know, love, and cherish.
