Clockwerk soldiers, airships, and aether bombs have ground the War Between the States to a stalemate. Can Colonel Julius Montclair find a way to end the bitter conflict?
 
Colonel Julius Montclair has been humbled by war. He wants nothing more than to simply do his job and is more than ready to lay down the mantle of “hero”. That is, until President Grant himself summons Montclair to Washington. Montclair is tasked with a deadly mission: He must lead his troops on a clandestine insertion behind enemy lines, but he won’t be able to do it alone. He’ll need the help of the most dangerous and least trusted weapons in the Union’s arsenal - the spymasters of the Department of Strategic Intelligence.
 
Scarlet is a gorgeous young DSI agent and trained assassin. She has the lethal skills and gritty determination required to protect her country. But can she gain the trust of Montclair before it’s too late to stop a dark aether-fueled weapon of mass destruction from erasing the Union from history?
