The Redwall Trilogy: "Redwall", "Mossflower" and "Mattimeo"

Redwall Abbey is a peaceful community of mice, and its quiet life is put at risk by Cluny the Scourge, a one-eyed rat warlord who leads a large army of hardened predators. Cluny expects the abbey to fall without much trouble. He has not counted on the bravery of the Redwall mice and the woodland creatures who stand with them, nor on Matthias, a young novice whose strength and resolve reach into the most frightening dreams of his enemy. This collection gathers three linked adventures from the Redwall world, full of battles, loyal friends, and a struggle between good and evil.
