The sky city of Valusha is now ruled by an evil overlord called Jenta-Lor. The former ruler and wizard, Obsidian has gone into exile, and has not been seen for many years. There's a weird band of misfits - a boy, an engineer and a wizard who have all been locked away in Skytraz Prison. No one has ever escaped from there - well it is thousands of feet above the earth. All seems hopeless. But the wizard prisoner Rebus knows the layout of Skytraz Prison, so there just might be a chance to break out and get away. If so, can they find Obsidian, and what dangers are ahead? Buckle up; there's Magic, Sky Ships and Dragons in this roller coaster adventure ride.
