Ganymede

The third book in the Clockwork Century series, following Cherie Priest's steampunk adventure — and runaway hit — Boneshaker and its sequel, Dreadnought

The air pirate Andan Cly is going straight. Well, straighter. Although he’s happy to run alcohol and guns wherever the money’s good, he’s not sure the world needs more sap, or its increasingly ugly side effects. But reforming is easier said than done: the captain’s first legal gig will be paid for by sap money, because the Seattle Underground is in dire need of supplies.

New Orleans is not Cly’s first pick for a shopping run. He loved the Big Easy once, back when he likewise loved a beautiful mixed-race prostitute named Josephine Early, but that was a decade ago. He’s still on Jo’s mind, he learns when she sends him a telegram about a peculiar piloting job. It’s a chance to complete two lucrative jobs at once. He sends his old paramour a note and heads for New Orleansl, with no idea of what he’s in for — or what she wants him to fly.

But he won’t be flying. Not exactly. Hidden at the bottom of Lake Pontchartrain lurks an astonishing war machine, an immense submersible called the Ganymede. This prototype could end the war, if only anyone had the faintest idea of how to operate it… if only they could sneak it past the Southern forces at the mouth of the Mississippi River… if only it hadn’t killed most of the men who’d ever set foot inside it.

Now the only question is whether Cly and his crew will end up in the history books, or at the bottom of the ocean.
