Pakistan, 2083 AD. Allah has burned the sky away. A mysterious snow falls over everything. Is it an endless winter? Is it the result of a nuclear exchange with India? A celestial impact? Now a barren wasteland, what little is left of Pakistan is heavily segregated along religious lines. For Avaan, a gun in the hand feels as natural as breathing. An apostate pariah living under martial law and religious bigotry, violence has become a way of life. What respite he had from this terrifying world — his brother, his family, and Doua, the love of his life — was snatched away in military raids. Now broken, Avaan finds himself involved in a civil war that poisons everything he's ever believed in. The army shadows his every move, a mob boss wants him dead, and a legendary resistance leader has taken a keen interest in him. But there is a ray of hope: Avaan discovers that Doua is alive. Obsessed with finding her, he takes a stand against the army, the mob, and Pakistan itself with the only thing he has ever been able to count on: the gun in his hand.
