1954: The Winter Soldier is the Soviet Union's greatest weapon. Assigned the most dangerous covert missions from the USSR's secret military branch, and guided by a handler who knows him better than he knows himself, he has only one purpose: to obey orders. But he wasn't always the Winter Soldier ... 1941: As World War II begins, sixteen-year-old Bucky Barnes is determined to enlist in the US army-if only the local commander will stop getting in his way. When Bucky is offered enrolment in a training program with the British Special Operations Executive-the UK's secret service-he leaps at the chance to become a hero. But Bucky has hardly touched down in London when he finds himself running from a mysterious assassin and accompanied by an English chess champion fond of red lipstick and double crosses. She's in possession of a secret every side is desperate to get their hands on. If only they knew what it was ... Decades later, the Winter Soldier struggles to solve the same mystery Bucky is just beginning to uncover. As their missions intersect across time, their lives collide too-in a way that neither of them would have expected, and that will change the course of their respective wars.
