After a brutal Civil War, America is a land divided.

As commander of her nation's border guards, Ever is a warrior sworn to protect her country and her queen. When an airship attacks and kills the monarch, Ever must infiltrate enemy territory to bring home the heir to the throne, and the dirigible Dark Hawk is her fastest way to the Union.

Captain Spencer Pierce just wants to pay off the debt he owes on the Dark Hawk and make a life for himself trading across the border. When the queen's assassination puts the shipping routes at risk, he finds himself Ever's reluctant ally.

As they fly into danger, Ever and Spencer must battle not only the enemy but also their growing attraction. She refuses to place her heart before duty, and he has always put the needs of his ship and crew above his own desires. Once the princess is rescued, perhaps they can find love in the Badlands—if death doesn’t find them first...
