When his friend Brent suggests they search for treasure in the hills surrounding their Tucson suburb, Winn joins him and puts his newfound skills to use. They discover a cave filled with mutated ghosts possessing unusual powers. Here, Winn finds something so incredible, it begins a nightmare that will haunt him for the rest of his life.Winn's mother is distant and uninterested in mentoring his abilities, so Winn turns to Marty, a neighbor who steers him toward a solution. On the way, they meet Jeanette, a crazy but prophetic resident of their trailer court, and Ida, a firecracker who gave up part of herself to confront a similar nightmare.If the ghosts in the cave were normal, Winn and Brent might stand a chance. But the ghosts are downwind, where radiation changed everything...The Impossible Coin is a fast-paced adventure with an unusual twist on ghosts. It is the second book in The Downwinders Series, but can be read stand-alone.
