Roberts, Willo Davis

Lewis and Alison's vacation should be lots of fun. Driving to Yellowstone National Park in a motor home, seeing all the fantastic sights, getting to know their new neighbors... the trip should be a blast. It turns out to be anything but. First they discover that their hosts, the Rupes, have no interest in their own children. Even worse, two strange men seem to be following them. Could they have somthing to do with the one-hundred-dollar bills little Billy Rupe keeps finding in the motor home? Lewis is afraid the answer is yes -- and he should be.

Though Rob saw Mrs. Calloway fall to her death, strangled by the leather strap of her binoculars, he wants to believe that it was an accident. He wants to pretend he didn't see the hands that pushed her out of her window.

A ten-year-old girl, who has always looked different from other children, discovers that she not only has unusual powers but that there are others like her.

When the Minden Curse involves Danny with the old Caspitorian house, he discovers the secret of its hauntedness and lost treasure and helps foil a schemer who wants both the house and treasure.
