Idaho

One hot August day a family drives to a mountain clearing to collect birch wood. Jenny, the mother, is in charge of lopping any small limbs off the logs with a hatchet. Wade, the father, does the stacking. The two daughters, June and May, aged nine and six, drink lemonade, swat away horseflies, bicker, sing snatches of songs as they while away the time.

But then something unimaginably shocking happens, an act so extreme it will scatter the family in every different direction.
