Four Best Friends.

And Then One Went Missing . . .

In college, Griffin McCray and his three best friends had their lives planned out. Griffin and Luke Gallagher would join the Baltimore PD. Declan Gray would head to the FBI and Parker Mitchell would go on to graduate school as a crime scene analyst. But then Luke vanished before graduation and their world--and friendships--crumbled.

Now Griffin is a park ranger at Gettysburg, having left life as a SWAT-team sniper when a case went bad. The job is mostly quiet--until the day he captures two relic hunters uncovering skeletal remains near Little Round Top. Griffin just wants the case to go away, but charming forensic anthropologist Finley Scott determines that the body is modern--a young social justice lawyer missing since spring--and all evidence points to the work of an expert sniper. When FBI agent Declan Gray takes over the case, past and present collide. Griffin soon realizes he'll need to confront some of the darkest days of his life if he--and those he cares about--are going to escape a downward spiral of murder that crosses continents.
