I’m looking for a book I read in middle school (most likely) or high school: A young girl(?) either moves in with a new family, or a new house. She plays in the woods and the local dump. Her parents warns her to not play in the abandoned fridges/freezers because children get trapped in them. At some point there is either talk of, or discovery of a man living in the woods – he is slow minded. He is seen positively by the girl. Later this man is found by her inside a fridge/freezer in the dump. This is the first time she has been confronted by death.
