The Haunting by Jo Wilde

Micki is in trouble again. A Ghost of a former school mate is haunting her to find the vampire responsible for her death. 

Meanwhile, T-Dawg - Candy's big brother - has returned from Afghanistan and blames Micki for the disappearance of their father. While Candy and Micki's relationship becomes difficult, Valentine returns in Micki's life, and something has drastically changed about him.

Can Micki still trust Valentine, and why do young girls keep popping up dead in the Louisiana swamp? It will take all of Micki's resolve to figure out what is going on in the small town of Eastwick Louisiana.
