The Dark We Know by Wen-yi Lee
If you’re looking for scary, this one is being compared to several excellent horror reads, including She Is a Haunting, IT, and The Haunting of Hill House.
Isadora Chang hated growing up in Slater, which felt repressive. But it only got worse when two of her best friends died. Isa knows she can’t stay in Slater or she’ll be swallowed whole, so she runs away, leaving behind her last friend Mason.
But then Isa’s father, who was abusive, dies, and she has to come back to Slater. If she goes back to school for a bit, she’ll be able to collect an inheritance. When she arrives, she’s met by Mason at the cemetery.
Mason is convinced that their friends were murdered by the evil spirit of the town, and he’s begging Isa to help him find out the secrets Slater is keeping. Isa’s unsure until she begins to have a series of strange experiences and worries that Slater is gunning for her next.
