Airborn is a steampunk novel by Kenneth Oppel. It is sequeled by Skybreaker, which is followed by Starclimber. It chronicles the adventures of Matt Cruse and Kate DeVries, two teenagers living in an alternate past where massive zeppelins roam the skies and France and Canada are the rival technological rulers of the time. Matt is a pilot's apprentice, and longs to fly an airship as captain like his late father did. He is in love with Kate. Kate is a suffragist, a cryptozoologist and the lover of Matt, and she uses her skill in arguing and the frightening way she flares her nostrils to always get her way. Together, they have many adventures in the sky, escaping pirates, finding gold and discovering a whole aerial ecosystem.
