It’s mid-August of 2016, and the Hallorans invite Hollis and Carrie Joplin to spend the weekend at Healey and Caldwell’s golf retreat at Wolfscratch in the North Georgia mountains. Although a very pregnant Carrie is happy to escape Atlanta’s steamy heat, Hollis is afraid she’ll overdo it on the hiking trails. But when the four of them discover a dead body at the Upper Falls, that’s the least of his worries.
When the local authorities refuse to investigate what Hollis is certain is a homicide, it sets off a chain of events that will lead him to the United Daughters of the Confederacy, and from there to a white supremacy group called The Cause, dedicated to righting perceived wrongs resulting from the Civil War. Many of the members are participating in a reenactment of the Battle of Tunnel Hill, a town not far from Wolfscratch.
Working with the Georgia Bureau of Investigation, Hollis Joplin and Tom Halloran find themselves up against a domestic terrorist plot that threatens to open old wounds and spill more blood.
