Murder of Angels — Caitlin R. Kiernan

Ten years ago, Niki Ky and Dania Parker saw something unspeakable in an old house in Birmingham, Alabama. Dania has denied it, escaping into a frantic music career and various addictions. But Niki hasn't been so fortunate. Diagnosed schizophrenic, she's lost years in a haze of therapy and antipsychotics. Now terrifying fragments of waking nightmares are reaching out to her, ghosts and demons driving her toward revelation and release, and she has begun to doubt that all the cracks in her reality are hallucinations.

Her dead lover Spyder Baxter is calling to her from another world, an alien, impossible place where Niki is known as the Hierophant, a feared and prophesied sorceress who can open a portal between worlds. Forces of darkness and light are at play across the highways of America, forces that move inexorably toward the abandoned house that Niki and Dania have spent ten years trying to forget. And Dania will finally have to face what really happened there if she's to help Niki save a world...or destroy it.
