The Hollow Below

Set in 1940 in the decaying asylum of Gehenna Sanitorium, The Hollow Below is a psychological horror novel that explores the fragile boundaries between delusion, memory, and the supernatural. Dr. Constance Adler arrives at Gehenna under the premise of restoring order to a crumbling institution buried deep in the forests of Tartarus Falls. But the longer she stays, the more her reality begins to fray. Patients suffering from rare psychological disorders-Cotard's Delusion, Delusional Parasitosis, Fregoli Syndrome, and others- appear to be linked not only by madness, but by a shared vision of an entity they call the Hollow. The staff grows increasingly unreliable. Time loops. Mirrors lie. And Constance finds herself uncovering secrets from her own childhood tied to Alma Adler, a long-dead doctor whose final experiments may have cursed the grounds forever. Structured through chapters, diary entries, patient records, and journal fragments, The Hollow Below is a descent into institutional horror that merges the internal terrors of mental illness with external supernatural dread. It explores inherited trauma, medical abuse, the nature of identity, and the possibility that sometimes, the voice telling you you're insane... might be trying to warn you.
