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. It is not long before the twins stumble upon a map and an unusual key that leads them through a portal to another time, and a world filled with mystical creatures. As a princess pleas with the teens to rescue an innocent family from a fate worse than death, they soon uncover not only the secrets of the past, but also the mission of evil beings determined to win at all cost.
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.
