Mercy river - Glen Erik Hamilton

When Van Shaw receives a distress call from his fellow Afghan War veteran, Leo Pak, he has to leave the urban hazards of Seattle to head far south to a town called Broken Ridge, deep in the wild heart of rural Oregon.

Leo faces charges of murdering a local gun dealer, and while Van doesn't doubt his friend's innocence, he knows he faces conviction.
As Van starts his own covert investigations, the small town is suddenly awash with Army Ranger veterans, converging for a raucous annual Rally.
Was it only this reunion that brought Leo to town?
Or is someone at the Rally setting Leo up to cover for their own dark designs?
