7th&up. This snarky and humorous homage to Buffy the Vampire Slayer is slight and fluffy fun. 
 A highschooler on the fringe, Mia can't believe her luck when she's asked to prom by Rob (a handsome, intellectually challenged but sweet football player.) When popular and evil Samantha tries to steal him away, Mia decides that measures must be taken- in the form of a love spell. 
 Things go horribly awry, and the entire student body slowly starts turning into zombies. Mia will need the help of her best friend Candice and the seriously cute and intense new boy Chase to save the students, herself and prom.
