The siblings are pressed to use their skills and wits as they face the trials of being alone and afraid. Not only do they have to find food and shelter, but they quickly learn that there is something very unusual about the mountain they are lost on. They are threatened by natural disasters as well as evil creatures who seek to harm them and trap them and fill them with fear and doubt. When the siblings get separated and the evil creatures capture Socorro, they almost give up hope of ever surviving and finding their parents again. But during these extreme trials they also discover (with the help of some very unusual woodland friends), that they can overcome the evil if they fight with all their spiritual might!
