But after their father purchases a large estate in northwestern Idaho, they are thrilled to begin a new adventure in the mountains. Little do they know that their lives are about to change forever. As soon as Henry and Haley are introduced to the diverse group of mysterious characters that inhabit the small town of Bonners Ferry, they learn of a tragedy hundreds of years ago that spawned the kind of legend that has always kept the locals wary and suspicious.

In a strange world filled with magic, wonder and beauty, Henry and Haley must abandon their childlike innocence and demonstrate to everyone all the ways humans can overcome seemingly impossible odds.
