The adventure continues in this 4th book in the Cloudland series, Cloudlands & Darklands (approximately 195 pages). Blueworld has been struck by a dangerous lightning weapon, yet the rogue leader who developed it isn't on Cloudland or Darkland. King Nature calls on Jane, Robbie, Neely, and Neely's sister Imani to help. But on their way up to Cloudland they are attacked by a violent wind and separated! The girls will fly between different lands to help put up a shield, and to provide coordination with the boys, prisoners in the rogue leader's castle. They will battle new creatures and encounter life-threatening dangers in trying to bring down this madman before he strikes again. And to do it, they will have to team with their former Darkland enemy, King Rydzat!
