Every Foul Spirit by William Gorman (paperback)
So . . . what am I told?
A familiar small town. A wrathful, metamorphic killer with supernatural abilities. A young girl whose time has come—angel of life, and death—is the only one who can stop his unspeakable deeds.
Katie Franklin has turned twenty-one at last, and been released from the Ransom Sanitarium. And hell has been released with her. Now it’s back to the Val, where monsters are real . . .
Something evil is stalking the shadows of Blackwater Val, and it wants lifeblood and flesh. What she finds waiting in the unhallowed darkness there will forever haunt her—and you. Return with her if you dare. To see the dead children. Feel their torment. To face the old terror.
