Made of Steam and Stardust (Paperback) (ISBN-13: 9798889170495)

When a comet hurtles toward her planet, sixteen-year-old inventor Gerdie is determined to stop it and use her success to improve the conditions of the factories she works in: she'll build a machine that will save the world.

But as she hunts for the parts to build her creation, she encounters Fell-a mysterious boy with an unsettling connection to the comet. He's being hunted by the ruthless Conqueror Seki, and soon Gerdie is, too.

On the run, the duo uncovers a chilling secret: blueprints for a deadly army of automatons. The army is nearly complete, but a final piece is still missing.

If Gerdie doesn't find it before Conqueror Seki does, the comet will be the least of her worries.
