Mad Marienne (Paperback) (ISBN-13: 9798988740902)

Only luma turns machines into miracles.

Only Luma Barons know how to collect luma.

Only sky pirates dare to oppose them.

Separated from her brother, Katherine has spent the past two years as an indentured maid in an effort to pay off her father's debt to Luma Baron Prescott. As her continual mistakes repeatedly add to that debt, reuniting with Ethan seems an impossible dream.
But when she is kidnapped by sky pirates, a new opportunity arises: join the crew and rescue Ethan herself.
Katherine's doubts about the sky pirates increase as Captain Marienne struggles to stay ahead of her enemies. With Luma Baron Prescott hunting after them, will Katherine and Marienne be able to maintain their freedom?
