From the #1 New York Times bestselling author of the Reckoners series, the Mistborn trilogy, and the Stormlight Archive comes the second book in an epic series about a girl with a secret in a dangerous world at war for humanity´s future. All her life, Spensa´s dreamed of becoming a pilot and proving herself a hero like her father. She made it to the sky, but the truths she learned there were crushing. The rumors of her father´s cowardice are true--he deserted his Flight during battle against the Krell. Worse, though, he turned against his team and attacked them. Spensa is sure that there´s more to the story. And she´s sure that whatever happened to her father that day could happen to her. When she made it outside the protective shell of her planet, she heard the stars--and what they revealed to her was terrifying. Everything Spensa has been taught about her world is a lie. Humankind has always celebrated heros, but who defines what a hero is? Could humanity be the evil the galaxy needs to be protected from? Spensa is determined to find out, but each answer she discovers reveals a dozen new questions: about the war, about her enemies, and even, perhaps, about Spensa herself. But Spensa also discovered a few other things about herself--and she´ll travel to the end of the galaxy to save humankind if she needs to.
