Which 2023 Horror Novels Focus On Psychological Terror Over Gore?

Okay, last one from me (for now): 'The Book of Secrets' by Melissa McTernan is a deep-cut indie title. It's about a town where everyone's secrets are literally turning into physical, monstrous manifestations. The slow-burn is watching the community fracture under the weight of their own hidden shames and fears, and the protagonist's race to understand the phenomenon before her own secret destroys her. The horror is intensely personal and psychological, dealing with guilt, shame, and the terror of being truly known. It's a brilliant metaphor executed with creeping tension.

Man, 2023 was a weird year for horror. The books that stuck with me weren't the ones with monsters in the dark, but the ones where the dark was already inside the house, you know? Megan Chance's 'A Light in the Forest' absolutely wrecked me for weeks. It's a slow, creeping dread about a family unraveling after a loss, and the psychological horror comes from the unreliable narration—you're never quite sure if the threat is supernatural or just profound, devastating grief. It's not a book you read so much as you survive, and the ending left me just staring at the wall. I also kept thinking about 'Whalefall' by Daniel Kraus, though some argued it was more thriller. For me, the real terror was the claustrophobia, both physical and emotional, of being trapped with the memory of an impossible father. The monster is almost secondary to the psychological landscape it churns up. It’s a different kind of fear, less about jumps and more about a deep, existential pressure. A real sleeper hit for me was 'The September House' by Carissa Orlando. The premise sounds almost funny—a woman decides to just live with her haunted house—but the execution is a masterful, heartbreaking study of enduring domestic horror and the coping mechanisms we build that become their own prisons. The fear is quiet, cumulative, and deeply unsettling.

I'm blanking on the title, but there was a book about a therapist and a patient sharing a recurring nightmare... or was it a shared delusion? Ugh, it's on the tip of my tongue. The premise alone was psychological horror gold. Maybe someone else here knows it?
