Bravelands: Books 2-6 by Erin Hunter (Ex-Library HC/DJ)
An elephant who can read the bones of the dead.
A baboon rebelling against his destiny.
For generations, the animals of the African plains have followed a single rule: only kill to survive. But when an unthinkable act of betrayal shatters the peace, the fragile balance between predators and prey will rest in the paws of three unlikely heroes.
