(Book)

Now a nascent demon-hunting crew on the lam, Danielle and her friends arrive in a small town that contains a secret occult library run by anarchists and residents who claim to have come back from the dead. When Danielle and her crew investigate, they are put directly in the crosshairs of a necromancer's wrath--whose actions threaten to trigger the apocalypse itself.
