For fans of THE HUNGER GAMES, DIVERGENT, and THE MAZE RUNNER. Seventeen-year-old Ada always knew her life was destined to suck. Being born with a rare, unknown disease that makes her frail and sickly has ostracized her from the rest of her agricultural village, and although high school graduation promises a new start in one of the satellite villages, she's confident that she's going to die alone. Especially since her twin and his best friend, Zeran - the only one who's ever treated her like a person - are too exceptionally smart and strong for their own good. And with folklore about a secret gilded society where "the chosen ones" go circulating the air her crap lungs can't breathe, she's even more confident she'll never see Zeran again. But then graduation comes. And everything she thought she knew of herself and the system is challenged. Turns out that secret place is real. And she might have the key to get there - her "defective" DNA.
