Into Darkness — Richard Fox

A deadly ambush leaves two Soldiers in terrorist hands, and their only chance at rescue is the connection between Captain Eric Ritter and the Al Qaeda mastermind behind the attack. To find the lost Soldiers, Ritter must ally with the Caliban Program, a covert arm of the CIA that gives him remit to use any means necessary in his search; means forbidden by his oaths as an officer. Written in the brutally honest voice of an Iraq War veteran; Fox's experiences bring an edge of pathos and undeniable authenticity to the book.
