The Mercenary Pirate by Katherine Bone

What if your favorite superheroes had Regency-era doppelgangers? And what if a group of them were recruited by the Duke of Wellington to gather intelligence for him during the Napoleonic Wars while they protected their own parts of the realm?

Wolfgang, one of Lord Wellington’s craftiest spies, is a fighter, an indulgent loner who is cunning and bold enough to go where others do not dare. He hates distractions and complications, especially those involving the fairer sex, and his instincts have always fueled him and kept him on course, mission after mission. That is, until his talents steer him toward a destiny he didn’t know he had and a search for the brother he barely remembers. And when he comes into contact with a brave young woman disguised as a boy, the urge he feels to protect her might just lead him on the biggest adventure of all.

Selina’s wedding day did not go as planned. Instead, she was kidnapped by pirates and ransomed for an exorbitant sum. Her diabolical captors didn’t hold up their end of the bargain, however, and kept her imprisoned even after their demands were met. More clever than her kidnappers expected, she managed to escape and disguised herself as a boy. Forced to lie, cheat, and steal in order to stay alive, she loses hope of ever returning to the man she intended to marry. Desperate, she agrees to become a handsome and compassionate sea captain’s cabin boy to gain passage back to Cornwall, but the captain endangers the one thing she cannot afford to lose—her heart.
