Shattered Veil — Tracy E. Banghart

When everything that defines you is stripped away, who do you become? For Aris, a talented wingjet pilot, war means sacrificing everything: her home, her name, her face-and the one promise she swore she'd never break. In the small village of Lux, everyone flies wingjets, but nobody flies them like Aris Haan. When she's not dancing through the skies, she's spending every minute with Calix, whom she's loved since childhood. They plan to Promise, but instead he is sent to defend their dominion against a bloody invasion. Determined not to lose him, Aris follows, joining an underground network of women inside the male-only military. Using secret technology that allows her to pass as a man, she becomes "Aristos," a Flyer in a search-and-rescue unit. As Aris grows stronger on the battlefield and more comfortable in her guise as Aristos, her personal mission becomes less and less clear. When she and her enigmatic commander, Major Vidar, uncover an astonishing conspiracy that could destroy everything, she must make a choice that will determine not only the fate of her heart, but the future of her dominion.
