Unmanned - Dan Fesperman

As an F-16 fighter pilot, Darwin Cole was a family man on top of his world. Now he's a washout - drunk and alone in a trailer in the Nevada desert, haunted by the memory of an Afghan child running for her life from the Predator drone he 'piloted'. Reluctantly, Cole teams up with three journalists seeking to discover the identity of the anonymous intelligence operative who called the shots in that ill-fated mission.
But in a surveillance culture, even the well-intentioned must sometimes run for their lives. Especially when they're tracking leads to the very heart of that culture - in intelligence, in the military, and among the unchecked private contractors who stand to profit richly from the advancing technology... Technology not just for use 'over there', but for right here, right now.
