The most dangerous pirate in the skies might be the one who steals your heart. Yvette Séverin has piracy in her blood. The only child of the vile Captain Redbeard, she has commandeered his name, his best smuggling routes, and a perfect airship. Now she's determined to shove all her past failures aside and make herself the best possible captain. The new Captain Redbeard leaves no woman behind. If protecting her crew leads to kidnapping a prim and proper-and irresistible-psychologist... C'est la vie. The last thing Catalina Navarro needs is an alluring and chaotic pirate upending her orderly life. The offer to join Redbeard's crew of unconventional women is tempting, but Lina will only accept under her own terms: It's a job, and it's only for a few months. When her attraction to the pirate captain swells into something undeniable, Lina lays down the rules again: The affair will be casual, private, and temporary. But when mechanical monsters attack the pirates and threaten civilians, Yvette and Lina will be flung headlong into an ocean-spanning whirlwind of danger and intrigue. With enemies on their heels, they must rely on old friends, new crewmates, and on one another. Teamwork means time together, and soon Yvette and Lina will question both their intimate arrangement and their long-held beliefs. Saving the world won't be easy. But it might be possible if the captain and her mate can open their hearts and fight side-by-side.
