In the middle of a wintry night, deep in the forest, Urso Brunov hears a cry for help carried over the cold winds. Wolves are on the prowl and two young polar bears are lost in the forest. Though he may be the size of a thumb, who is Urso Brunov if he is not the Little Father of All Bears? Traversing snow-laden forests on the backs of stags and crossing wide seas atop a whale, this tiny yet brave hero returns the two lost polar bear cubs to the Land of Rainbow Lights - and is treated to a grand celebration in the land of ice before returning home in a wondrous moonlit flight on the back of a goose.

In the age-old tradition of tall tales, Redwall author Brian Jacques shows us storytelling at its finest in this spirited adventure.
