Bert, a young boy who's lived in an orphanage longer than he can remember, with no friends and the most ordinary life, is told that magic is just a myth. But then a chain of strange and inexplicable mishaps causes Bert's life to spiral out of control -- only to be rescued by Finch, a plucky girl-adventurer with metal legs, and soon the two are sailing across a sea of clouds with the mysterious Professor, pursued by a royal prince who's desperate to get his hands on Bert at any cost. For magic is all too real and even more powerful than imagined -- and Bert just might hold the key to bringing it back to the world.
