Runt the Brave: Bravery in the Midst of a Bully Society (Legends of Tira-Nor Series #1)

Driven by their blood-frenzied master, a merciless army of rats swarms toward the underground mouse-city of Tira-Nor. Only one mouse has the courage to face the onslaught, the "runt" JaRed, son of ReDemec. But JaRed is about to encounter a power beyond the rat army, beyond even that of the Great Owl ... a power that will fling him into a destiny wilder than anything he could have even imagined!
