William F. Thornburgh

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

Fifteen-year-old Valya knows what it feels like to fly. She's a pilot who's always felt more at home soaring through the sky than down on earth. But since the Germans surrounded Stalingrad, Valyas been forced to stay on the ground and watch her city crumble. When her mother is killed during the siege, Valya is left with one burning desire: to join up with her older sister, a member of the famous and feared Night Witches - a brigade of young female pilots.
