Piper sees the Mark of the Dragonfly for the first time when she finds an unknown girl amid the wreckage of a caravan in the Meteor Fields.
The girl doesn't remember a thing about her life, but the intricate tattoo on her arm is proof that she's from the Dragonfly Territories and that she's protected by the king. Which means a reward for Piper if she can get the girl home.
The one sure way to the Territories is the 401, a great old beauty of a train. But a ticket costs more coin than Piper could make in a year. And stowing away is a difficult prospect; everyone knows that getting past the peculiar green-eyed boy who stands guard is nearly impossible.
Life for Piper just turned dangerous, a little bit magical, and very exciting...if she can manage to survive the journey.
