For fans of The City of Ember and The School of Good and Evil, The Mark of the Dragonfly is a fast-paced adventure story about a mysterious girl and a fearless boy, set in a magical world that is both exciting and dangerous.    Piper has never seen the Mark of the Dragonfly until she finds the 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.[STAR] "This magnetic middle-grade debut...[is] a page-turner that defies easy categorization and ought to have broad appeal."-Publishers Weekly, starred[STAR] "Heart, brains, and courage find a home in a steampunk fantasy worthy of a nod from Baum."-Kirkus Reviews, starred[STAR] "A fantastic and original tale of adventure and magic...Piper is a heroine to fall in love with: smart, brave, kind, and mechanically inclined to boot."-School Library Journal, starred
