Every October feels like a repeat of the best kind of chaos. The families — the Rizzos, the Van den Berghes, the Darrows, the Andersons, and the Mathieus — have been doing Halloween together for as long as anyone can remember. Their parents met in college, and now every year the tradition continues at the shared family house by the lake. It’s early morning on Halloween, sunlight barely peeking through the trees, and the big wooden house already smells like cinnamon pancakes, pumpkin candles, and the faint hint of costume glue.
