While most students at Burtonwood Academy get to kill demons and goblins, fifteen-year-old Emma gets to rid the world of little annoying fairies with glittery wings and a hipster fashion sense. She was destined to be a dragon slayer, but cute and charming Curtis stole her spot. Then she sees a giant killer fairy--and it's invisible to everyone but her! If Emma has any chance of stopping this evil fairy, she's going to need help. Unfortunately, the only person who can help is Curtis. And now, not only has he stolen her dragon-slayer spot, but maybe her heart as well! Why does she think it's going to be a fairy bad day?
Emma's plans to be a dragon slayer are ruined when she is assigned to slay fairies instead.
