There's something dark and angry in the barn. When four friends investigate a private home where rocks of mysterious origin land on the roof, a red light bounces around inside, and a marble has a will of its own, the situation quickly becomes intense. Can they help the homeowner find answers and gain peace, or will they lose to an entity's age-old hostility? Rayna, Sam, Barb, and Wolf are on the case in this sequel to The Tritium Hypothesis.
