The Dark Secret of Weatherend is a gothic fantasy novel directed at child readers.

Anthony and Myra Eells are touring the countryside near their hometown in Minnesota when they pass the old Weatherend estate, a dilapidated mansion where the eccentric J.K. Borkman once lived.

Despite posted signs enforcing No Trespassing, Anthony and Ms. Eells explore the grounds and find grotesque statues symbolizing wind, hail, snow, and lightning and a small diary hidden in the floorboards of the garage.

Soon thereafter, Anthony and Ms. Eells are visited by Anders Borkman, the son of the man who built Weatherend, who has come to reclaim his father's book.

Terrifying weather that can only be created by magic begins sweeping through Minnesota and Wisconsin, and Anthony and Ms. Eells realize all too quickly the connection between the weather and what's happening out at the justly named Weatherend estate.
