"You're my best friend, Bella!" I shouted.

"You're mine!" she shouted back.

"I won't forget you!" I yelled.

"Never, never, never!" she hollered back.

Bella has a secret - one that she is very good at keeping. The secret is a den, hidden among trees on a muddy slope. Nearby, some foxes have a den of their own.

But when the secret is betrayed, the foxes' lives are put in danger, and so is a
special friendship.
