It's the biggest, coolest Bone book of all! Get it while it lasts! This book will not be kept in print! Three modern cartoon cousins get lost in a pre-technological valley, spending a year there making new friends and out-running dangerous enemies. Their many adventures include conning the local people in 'The Great Cow Race,' and meeting a giant mountain lion named 'Rock Jaw: Master of the Eastern Border'; They learn about sacrifice and hardship in 'The Ghost Circles'; and finally discover their own true natures in the climatic journey to 'The Crown of Horns!'
