Endling: The Last (Book 1), Katherine Applegate
Byx was used to being last. The last in her pack and family - the youngest and smallest. The last anyone believed would survive in their dangerous kingdom. Byx was not afraid to be the first to die. She just did not want to be the last to live. The endling. Now Byx is the last chance to save her kind. And the last hope for every creature in her world.
