Dimanche, by Fleur Oury

Clementine, a small girl-fox goes along with her parents to her grandmother’s… another unremarkable and boring day in the countryside. She suddenly discovers a hole in the garden hedge. Curious, she rushes through the thorns and ends up face to face with a really strange hairless boy: a real human! Clementine and her new friend manage to get in a whole series of games before it’s time to go back, covered in twigs and leaves, to her family. The little fox sees her grandma under a new light because they now share a precious secret.
