"An Incidental Reckoning" is the story of Jon Albridge and Will Roup, two high school friends now struggling with middle-age who meet once a year for a weekend camping trip. But the memories that bind them are not pleasant ones; decades ago Jon and Will became targets of a bully named Brody Stape, the friendship that emerged from their experience borne from a need to survive.
They still bear the scars.
Jon wants to leave the past in its proper place.
Will wants to get even.
On the second day of their trip, two bikers enter the campground to spend the night, and suddenly Jon and Will find themselves playing an uncertain game with the new occupants, escalating towards a troubling end. Before the events set off by the confrontation reach a conclusion, both men will be forced to face their past as it spills over into the present...and threatens to take whatever future they have left.
