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 Police Department, Declan Grey would head to the FBI, and Parker Mitchell would study to become a crime scene analyst. But then Luke vanished before graduation and their world—and friendships—crumbled. Now years later, Griffin has left the police and his friendships behind. Still trying to forget a case that went bad when he was a SWAT team sniper, he's living a quiet life as a park ranger at Gettysburg. Quiet until skeletal remains are uncovered near Little Round Top—and they aren't Civil War—era. Griffin just wants the case to go away, but charming forensic anthropologist Finley Scott discovers evidence pointing to the work of an expert sniper. When FBI agent Declan Grey steps in to take 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 crime, danger, and murder.
