When she sleeps, Gen becomes the dream walker, the demigod hero of another world. Every night, she fights to protect her home, the isolated mountain kingdom of Gilead, from being consumed by the brutal, imperialist techno-theocracy of Shail.Now, despite everything Gen has sacrificed in her struggle, her two lives are coming apart. Gilead is on the brink of starvation and through nightmarish experimentation, the empire has stolen the secret of dream walking and has begun sending assassins for Gen on earth, where she is powerless and vulnerable. Alone, crippled by the side effects of her medication, and betrayed by her closest friends in both worlds, Gen must now fight for survival at every turn... And she is losing.
