The blue cloak
(Book)

"Based on real events beginning in 1797 — Rachel Taylor lives a rather mundane existence at the way station her family runs along the Wilderness Road in Tennessee. She attends her friend's wedding only to watch it dissolve in horror has the groom, Wiley Harpe, and his cousin become murderers on the run, who drag their families along. Declaring a "war on all humanity," the Harpes won't be stopped, and Ben Langford is on their trail to see if his own cousin was one of their latest victims. How many will die before peace can return to the frontier?"
