Secret Agent Santa (Brothers in Arms: Retribution Book 4)

Christmas was supposed to be about joy and hope…not about thwarting terrorist plots 

Most covert agents weren't blessed with long careers. Mike Becker wasn't like most agents. On the cusp of early retirement, he's given one final assignment: babysit a single mother with a reputation for coming up with conspiracy theories. Except the bullets flying Claire Chadwick's way can't be dismissed. Now Mike will do anything to protect her and her son, and uncover the truth. A truth that places them at the center of a terrorist attack on Christmas Day. Mike's career may be coming to a blazing finish, but in this woman he finally has a shot at the redemption that's eluded him for so long.
