The Rocketeer's Daughter

Sixteen-year-old Marga Toth attends school, takes violin lessons, and belongs to the League of German Girls at Peenemünde on the Baltic Sea, where Nazi Germany secretly develops their infamous V2 rocket.
Marga also has a gift—one capable of disrupting the world's balance of power and one the Nazis and Allies will kill for—forcing her into a dangerous game of survival.
From Peenemünde's thundering launch pads, to Berlin's parlors, and London's war offices, The Rocketeer's Daughter captures the intrigue and danger of its time in a riveting tale where family, friendship, young love, and world domination collide.
