This is the fifth story in the series. Set in the 1812 war in New Orleans. Hannah Bonner is here with her half-brother and his wife, searching for her son stolen by Honore Poiterin, a merchant for a corrupt and powerful Creole family. They don't realise that war is about to descend on them putting them in jeopardy.
It's a series that I really have to read more of it, including Last of the Mohicans, which is the inspiration for this series.
