King's Daughter: Dr. Farkas III - Dr. Farkas, #3

The year is 1663 and newly-engaged Dieudonnée de Lourdes volunteers to chaperone a group of orphaned girls to New France as part of King Louis XIV's King's Daughters new immigration program. Aboard ship she undergoes a transformative experience that throws her life into an unexpected direction. A hundred years later, Dieudonnée is New France's strongest weapon in fighting the English on the Plains of Abraham.
And, unless she gets a bayonet through the heart, her thirst for blood will never be quenched.
