book 8 Mariel of Redwall
by Brian Jacques

It is a jolly time at the Redwall abbey. The birds are singing, the food is wonderful and everybody is happy. A lost mouse maid appears, all dirty and with wild manners. Her real name is not even certain to herself but one thing she knows, her father is a prisoner of the evil (and crazy) sea rat, Gabool the Wild. The young mouse maid (now named Mariel of Redwall) will go in a quest to liberate her father. With her will come the young mouse warrior Dandin (armed with the legendary sword of Martin the warrior), the hare Tarquin (always singing to he beloved Hon Rosie) and the young cellar hog Durry Quill. Their quest is long and risky but also the other Redwallers must be careful. A little sea rat crew who has run away from Gabool's army is trying to conquer Redwall.
