Queen of Swords — Sara Donati

It is the summer of 1814, and Hannah Bonner and her half brother Luke have spent more than a year searching the Caribbean islands for Luke's wife and the man who abducted her. But Jennet's rescue is not the resolution they'd hoped for. While captive, she gave birth to Luke's son but was compelled to surrender him to a stranger in the hope of keeping him safe.

To recover the infant, the trio must begin a journey that will lead them to New Orleans and to a powerful, corrupt family who now claim him as their own. But in a city on the brink of war, the Bonners' plans go awry, isolating them from one another. And when Hannah falls ill, only an old friend can save her--and only an influential stranger can engineer a miracle that will reunite her family.
