Redwall #3: Mattimeo book by Brian Jacques

The third addition to the beloved Redwall series takes place during the summer of the Golden Plain. Preparation for a great feast are underway at Redwall Abbey, and the young mouse Mattimeo is contributing his share of the labors. But Mattimeo is the son of Matthias, the guardian of Redwall Abbey, and it is this fact that makes him the target of a fiendish kidnapping plot contrived by the vicious fox, Slagar the Cruel. When Matthias and his brave followers abandon their homes and face enslavement for the return of their children, the captive Mattimeo stands to prove his worth--and an unexpected hero is born.
