Beyond Cloudland - 9798987714720

King Nature needs help for a land no one knew existed, the neighboring world of Darkland. Bad things are going on there and they may be related to the disappearance of Robbie's Uncle Josh. Robbie knows nothing of this until he and his friend Neely are summoned by the king and sent into Darkland. This weird land of perpetual half-light puts the boys in one dangerous situation after another. It's a race at the end to escape two armies and see if they can restore some order, with the help of the most mysterious being of all.
