When Chieftain Shagbark dies suddenly, his successor Acorn must step into his place. Acorn is sure his old friend has been killed, but he has his paws full when Sterling leads his band of outlanders and gangsters to take over the town — and he has dark magic on his side. Acorn must fight as never before for his tribe, his people — and his life. Fans of Erin Hunter and the Warrior series, and fans of the Redwall series, will enjoy this book.
