In this fifth volume of the BONE saga, Fone and Smiley Bone strike out into the wilderness to return a lost rat creature cub to the mountains. It doesn't take long before they run smack into Rock Jaw, "Master of the Eastern Border," an enormous mountain lion with a none-too-friendly disposition. Life gets even more complicated when they befriend a group of baby animals who are being orphaned by rat creature attacks. Everything comes to a head in an earth-shattering clash between Rock Jaw and Kingdok, the leader of the rat creatures.
- This volume wasn't as good, but it was still fun.
- Awww! Bartley!
- The beginning is hilarious and awesome!
- The whole book focuses on Fone and Smiley. I want to know more about Phoney, Thorn, Gran'ma Ben, and the others.
- The ending is sad.
- I hope Rock Jaw has a larger role to play. It would be weird for a new character to get his own volume, but all he does is chase the main characters around.
