What should a lonely girl do in the August heat if adults don’t even allow her to play quietly in the yard: “Don’t sit on the grass... go into the house... it’s time for dinner...”? Ten-year-old Winnie goes to the forest. But she has no idea what adventures await her in the silent thicket: a magical spring, a meeting with a mysterious family whose secret she will have to keep for the rest of her life, and even a crime in the name of friendship.
