Come Closer by Sara GranRead about another entry on the list.
This is one of the most terrifying books on demonic possession I’ve ever read, because it feels so uncannily real; like something that could actually happen to you, or to almost anyone. The main character, Amanda, is a successful architect in a seemingly solid marriage, when she becomes plagued by a demonic entity named Naamah. Naamah initially manifests as repetitive noises that occur only when Amanda is in her loft, followed by sensual, almost hypnotic dreams in which she and the beautiful demon grow increasingly closer; the entity bears an uncanny resemblance to the “imaginary friend” Amanda invented for herself to cope with a difficult childhood. What happens next is a gradual possession that leaves the reader wondering how much of Amanda’s casual new brazenness, deception, violence, and unbridled sexuality is simply a result of her own frustrated desires, rather than the demon’s dark whims—until it spirals into the kind of grotesque and utterly gripping horror show that leaves no doubt as to what’s happening.
