The Haunting of Vampire Valley - Vampire Valley, #3

After the final, monumental battle with the vampires and the resurrections of her husband and brother, Maggie awakens one morning with her back propped up against a tree on the side of the mountain with Mabin and Tommy nowhere to be found. She searches for them, and they seem to appear magically, but they soon find they'll have to cope with a terrifying world very different from the one they left before the resurrections.
Even though dead, the vampires have come back to haunt the valley and regain their powers, and they have nothing but ill-will for those who caused their deaths. While trying to rebuild their lives, Maggie and Mabin and Tommy fight against the vampire spirits that will do everything they can to destroy those who destroyed them. They build a small cabin in which to begin their lives, but at night out of the mud and slime below there are clawed hands reaching up to capture their souls.
Mabin and Tommy have a strange way of disappearing into the sky at night, and poor Maggie is left all alone to deal with the tens of thousands of vampire souls intent on a horrid revenge.
