Ascent is a secret history novel published in 2007, written by Jed Mercurio. It follows the career of Yevgeni Yeremin, an orphan of Stalingrad, from his days as a MiG-15 pilot in the Korean War, where he becomes a leading ace. However, at the end of the war he crashes in a plane bearing USSR insignia. Although rescued by North Korean troops he is felt to have risked revealing that Soviet aircrew participated in the conflict and on cessation of hostilities he is exiled in disgrace to a polar base. He has been befriended by one of his groundcrew, (throughout referred to as 'The Widow'), who follows him north, and he eventually marries her. He becomes a trainee cosmonaut, with little hope of a mission; he eventually volunteers for a risky mission to attempt a lunar landing ahead of Apollo 11,
