Vampire's Hunger

The Awakening In a post-apocalyptic wasteland, civilization no longer exists, and only the strongest survive. The few remaining humans must band together with supernatural beings to battle unspeakable evil-or all hope will be lost. Kimber Treat is an ordinary woman with an extraordinary gift: she can raise the dead. As a necromancer who works with the police, she communicates with murder victims to bring their killers to justice.
But after a normal session goes horribly wrong, Kimber realizes she's summoned something dark and sinister. She's unwittingly unleashed the apocalypse, and everyone blames her .
