The Cowboy and the Unicorn

Siblings Micah and Sarah visit their grandmother's lake house every summer, but they never imagined that a seemingly ordinary jaunt to the beach would lead them to an adventure of a lifetime. A remarkable find holds the key to a magical world known as Hogar Haven, a strange world where goblins rule and visitors are forced to fight for their freedom. When they befriend a cowboy in the magical land, they soon discover just how difficult life is for those trapped in Hogar Haven. Soon, they find themselves working with the cowboy to help him save his horse, but they don't have much time. If they don't hurry, they just may find themselves trapped in the mystical world. Can they find a way out before it's too late?
