Shadows on the Mountain (Bravelands: Curse of the Sandtongue, Bk. 1)

For generations, a troop of gorillas has lived in peaceful seclusion high above the Great Herd. But strange things are happening to the animals who call the mountain home. And when the Great Spirit issues a dire warning, three young animals - a gorilla and leopard fro the mountains and a gazelle from the plains - must venture into the unknown to prevent darkness from overtaking all they hold dear.
