OSIRIS by Eric C. Anderson: It’s a dilemma no Washington politician wants to confront: rescuing 5,000 Americans trapped in Baghdad. Taking on the challenge is a crusty Marine, an embattled Army officer, two Turkish spies and the ultimate cyber-warrior. Their enemy? An ISIS regime intent on carving out a new caliphate. Can they rescue an American embassy under siege by a weapon that even Washington’s military might can’t defeat.
