Midnight Snack (Graveyard Shift: The Adventures of Carson Dudley, Book 1‪)‬

Working the night shift at the local mini-mart, Carson Dudley has seen his share of weird - but never the kind that tries to kill you, drain your blood and stuff you in a dumpster. With an unlikely collection of hunters, including a trigger happy security guard, a techie co-ed and a nun with anger management issues, it's up to him to put a stop to things before he becomes the next MIDNIGHT SNACK!
