The Leopard Behind the Moon [Paasewe-Valchev, Mayonn]

There are three important laws in Ezomo's village: Do not go to The Valley, do not go out at night, and never, ever, ever open the magical door that protects them all. But when Ezomo encounters the leopard believed to have killed his father, he and his two best friends embark on a journey that leads them past the boundaries set by their elders.

With his friends by his side, Ezomo chases after the leopard, certain that it has the power to cure all. But in the process, he discovers the truth about his village. And that cautionary tales exist for a reason.
