"Brought to the flying city when he was only five years old, orphan Milo Quick has never known another home. Now almost thirteen, Milo survives one daredevil grift at a time, relying only on his wit, speed, and best friends Jules and Dagda. A massive armada of airships has surrounded Highgate's crumbling armaments. Because behind locked doors--in opulent parlors, pneumatic forests, and a master toymaker's workshop--the once-great flying city protects a powerful secret, hidden away for centuries. A secret that's about to ignite a war."--Publisher description
