Called by a Dragon

Visiting from London, Pete, Nat, and Will are looking forward to their summer holiday along the Jurassic Coast of England. While exploring, they stumble across a hidden cave and emerge into a land quite different from their own-Avalanya. With the help of the queen dragon Jessynta, the boys and their new Avalanyan friends investigate what happened to Avalanya and how they can stop it from happening to Earth.
