Sometimes the scariest place in the world is the edge of your own life.Seventeen-year-old Zaiya has grown up in Sheridan Court, the crumbling house at the end of a Sausalito street that everyone whispers about. Above it, on a wind beaten hill, there is a fenced off garden and a flat circle of concrete where a well used to be. On certain cold nights a strange light seems to rise from the ground and hum through the fog. The stories say that if you are tired enough, hurting enough, desperate enough, the glow will notice you. It will offer you a way to step out of your life and never have to come back.Zaiya thinks those stories are just local drama until the night her own thoughts start circling the same quiet exit. Pressured at home, overwhelmed at school, and terrified of disappointing everyone who believes she is the strong one, she follows the pull up the hill. What she finds at the edge is not a clean escape and not a simple haunting. It is a thin place, something old and hungry that presses on people exactly where they are already sore.She is not the only one who has felt it. Dev, Imogen, Malik, Ani, Luca and Jae have all had their own nights on the hill, their own private negotiations with the glow. Some almost stepped. Some already regret how close they came. When the house at Sheridan Court is threatened and the well begins to stir again, the group is pulled together whether they like it or not. If they want to survive what lives under the hill, they will have to do something no one has ever managed to do there. They will have to say no and mean it.Together they begin to experiment with a different way to live beside the thin place. They write rules on sticky notes and in secret notebooks. No noble sacrifices. Ask for help before the edge. Fun is not optional. Being tired is not consent for anything. You do not owe the world every piece of yourself just to prove you belong in it. The more they try to follow their own rules, the more the glow pushes back, twisting their fears, turning their worst thoughts into lures.As pressure at school, at home and online builds, the edge between staying and stepping becomes frighteningly thin. Zaiya and her friends will have to untangle the history of Sheridan Court, the truth about the crack in the hill, and the choices of the kids who came before them. The hill is not asking for heroes. It is asking for offerings. The only way out may be to refuse the story it keeps trying to tell and write a new one of their own.Set in foggy Sausalito streets, empty corridors and late night group chats, this contemporary speculative novel is about what it means to stand at the edge of something and decide to stay. It is about found family, the quiet power of saying I am not okay before it is too late, and the small stubborn rules that can pull us back from the brink. Perfect for readers who love character driven stories with a touch of the uncanny, Primordial Glow holds space for both the heaviness of wanting out and the fragile, luminous hope of choosing to live in the okay between.
