Young Adult Steampunk
Young adult steampunk is a subgenre of teen science fiction set in an alternate Victorian or fin de siecle world, incorporating both magic and anachronistic technology such as steam engines and clockwork devices.
Cassandra Clare's Clockwork Angel is a great modern-day example. The trend in the genre is for it to incorporate paranormal elements, as the worlds are often populated by vampires and werewolves.
If you write young adult steampunk, explore the subgenre to connect with other like-minded writers, workshop, and publish your book.
