Query: Spooky weirdness

My first foray into Koontz novels and I was happily surprised. Well paced, creepy, and just plain weird. In Koontz's hands, a windmill becomes the setting for chills of a psyche-nature. Refreshingly, the source of Ironheart's special power is not the expected one(s). A terrifying flashback involving a fastfood joint will stay with you a while, as will the Dutch-style windmill. Is it just a case of fearing fear itself? Read Cold Fire and find out!
