Rakkety Tam, Published in 2004 by Brian Jacques, Philomel Books

"From beyond the cold northern seas and lands of ice, a terrifying beast arrives on the shores of Mossflower Country: Gulo the Savage! With his crew of white-furred vermin, this creature out of a nightmare comes to murder his brother and seize the fabled Walking Stone. Nobeast is safe from the mighty Gulo, who feasts on the flesh of his enemies.

But something stands between Gulo and what he seeks: the ancient Abbey of Redwall. Who will come to the aid of Abbot Humble and his peaceful Woodlanders? The mercenary warrior from the borders, Rakkety Tam Macburl, that's who! With his mate Wild Doogey Plumm, the brave squirrel sets forth on a quest to rescue two kidnapped Redwall maidens, and joins forces with one hundred perilous hares from the Long Patrol. Together they face a battle that ranges far over the plains, streams and woodlands of Mossflower in this epic tale of war, courage and comradeship.

Hark to the battlecries: Redwaaaaaaal! Eulaliiiiiaaaa! Haway the Braaaaaaw! "

This Tale from Redwall introduces some interesting elements. First of all, it introduces cannibalism. I am glad Brian Jacques incorporated it with the evil side only, and that the good creatures are thoroughly disgusted with that aspect of their foes. I wouldn't read these books if the good side embraced the idea of cannibalism. Second of all, it introduces the tortoise, or the "Walking Stone".  This just could be the only book in which that type of creature is found. I think that it is funny that all the creatures in this book think that it is a seat or a rock that moves around. I just can't get over the fact that they are so ignorant. Over all, this is a good book.
