Hermione Granger is sick of being abused and bullied by her headmaster. She knows the light is not really the light, but Albus Dumbledore's dream world, where he controls everything. She has realised that she needs to escape and the only feasible way out is to become a Death Eater. Hermione wants to fight Dumbledore. However, she can't do it alone. Along the way, she meets Eleven Hopper, a girl who is fighting in the same war as she, just with different monsters. Eleven introduces Hermione to her friends, and they band together with the DeathEaters to defeat the monsters from the Upside Down and Albus Dumbledore and his followers.
