Federal agent Greg Marcotte and space reporter Justin Harris are counting on a relaxing Sunday to discuss their upcoming fourth anniversary and prepare for the hurricane that’s bearing down on them from the east. But their plans are interrupted when Greg’s boss calls. A construction crew at Cape Canaveral has uncovered a set of old bones, and it’s up to the Air Force Office of Special Investigations to—well, investigate. Greg, his partner Mindy Leonard, and the rest of the team are removing the bones from their shallow grave when they find a damaged rib bone and the bullet that likely did the damage. It’s the coldest of cold cases, but Greg, Mindy, and Justin won’t quit until they identify their victim. To their surprise, they may also be able to identify the killer.
