Maria Isabella Boyd’s success as a Confederate spy has made her too famous for further espionage work, and now her employment options are slim. Exiled, widowed, and on the brink of poverty…she reluctantly goes to work for the Pinkerton National Detective Agency in Chicago. Adding insult to injury, her first big assignment is commissioned by the Union Army. In short, a federally sponsored transport dirigible is being violently pursued across the Rockies and Uncle Sam isn’t pleased. The Clementine is carrying a top secret load of military essentials—essentials which must be delivered to Louisville, Kentucky, without delay. Intelligence suggests that the unrelenting pursuer is a runaway slave who’s been wanted by authorities on both sides of the Mason-Dixon for fifteen years. In that time, Captain Croggon Beauregard Hainey has felonied his way back and forth across the continent, leaving a trail of broken banks, stolen war machines, and illegally distributed weaponry from sea to shining sea. And now it’s Maria’s job to go get him. He’s dangerous quarry and she’s a dangerous woman, but when forces conspire against them both, they take a chance and form an alliance. She joins his crew, and he uses her connections. She follows his orders. He takes her advice. And somebody, somewhere, is going to rue the day he crossed either one of them.

Features a black pirate captain as one of the protagonists

Although she was orphaned at birth, Eden Moore is never alone. Three dead women watch from the shadows, bound to protect her from harm. But in the woods a gunman waits, convinced that Eden is destined to follow her wicked great-grandfather--an African magician with the power to curse the living and raise the dead. Now Eden must decipher the secret of the ghostly trio before a new enemy more dangerous than the fanatical assassin destroys what is left of her family. She will sift through lies in a Georgian ante-bellum mansion and climb through the haunted ruins of a 19th century hospital, desperately seeking the truth that will save her beloved aunt from the curse that threatens her life.
