This is the heartwarming story of hope, about a young girl whose love for a gorilla named Koko became a call to action for the future of all gorillas.

It is brought to life by Stella Machado (left), her family, teacher and classmates at La Honda Elementary school in Woodside, California (below) — a stone’s throw from where Koko and Penny lived their extraordinary lives together.
