Adventures, Victorian gentlemen and airships!

Mary Clipwood is a young and inexperienced inventor wishing for a life full of adventures. When her father's friend, Edward Harrington, builds a prototype airship and organizes an expedition following the tea route from China to London, she can't resist but to join.

There are, however, forces that do not wish the expedition to reach its destination. When political enemies clash and old grudges come back to life, Mary will find herself between fighting giants. She will have to learn to put everything at stake in order to succeed.
