Skyborn The Fallen (Book 2 of Skyborn)

Alice found her place among the heroes...
And then she gave it up.
Unable to stomach the methods of her fellow heroes, she stepped away from the very purpose she'd tried so hard to find. But now the world knows she exists, something stirs in the shadows, a mind bent on twisting the boundaries between heroes and villains. Alice finds herself pulled back to The Farm she'd walked away from to confront a threat she never imagined.
