Ida and Duffy are back! In the exciting follow-up to Girl in the Gears, the duo make their way to the Free City of New Orleans, where they plan to find some answers for Ida among the eclectic citizens of the dazzling city. Instead, they find themselves "recruited" as bodyguards for the city's Queen Mayor, who's on the run from an invading force, and swept up the river aboard a very special steamship: The Marie Curie! The current ahead is filled with spies, rogues, gunfights, and even an old flame or two. Can Ida and Duffy ride out the storm and survive long enough to find the answers they seek?
