Continuing with the adventures of Old West heroine Breanna Baylor, book six of the Angel of Mercy series begins with the planning of a wedding — between Breanna and the legendary Stranger, whose true identity has now been revealed. Before the wedding, however, John's best man, Chief U.S. Marshal Solomon Duvall, disappears. And after the wedding, both John and Breanna — who has pledged, "Whither thou goest, I will go" — put their own lives in danger as they set out to find him.
