Line of Departure. Pathfinders, #4

At Obsidian Ridge, combat instructor Dale Ricoh thinks he's unshakable-until a no-gloves sparring match with former Marine Ty Monroe ends in a kiss that feels like both contact and conquest. Oren Callaghan can't look away, even as the buried fragments of his captivity claw their way to the surface. Together, the three men are lethal; apart, they're unfinished. But when low-grade drones and a too-smooth recruit signal that the Ridge is being stalked, Dale, Ty, and Oren are forced to step across a new line.
To protect the family they've built and the home that remade them, they must face the ghosts of the past-and choose whether to stand together or fall apart.
