The book I read was Bone Rock Jaw Master of The Eastern Border By Jeff Smith. The 5th book in the Bone Series. The Plot of This book is when Smiley Bone befriends a rat creature cub and names is Bartleby. Fone Bone forces Smiley to return it to the mountains though because if people found that they are keeping a rat creature they will run out of that town too. So, when they are returning Bartleby to the mountains they run into Rock Jaw who calls himself Roque Ja. Continuosly Rock Jaw will try to kill them for no apparent reason but the fact that they don’t have a “side”. Finally they ask what he means when he says that. Rock Jaw says that since there is a huge going on with the Rat Creatures Vs. Dragons they must choose a side of Dragons or Rat Creatures. Later on Rock Jaw sees Kingdok and gets in a huge fight and ends up killing Kindok. Once they return to the valley they see that everything there was turned into a battle field. They could never find anybody. Any animal or thing they saw said that they were known for killing kindok.
