It's Big Night in Dunwiddle . . . and that means the whole school has a sleepover like no other. For one night every year, magic students run through the halls, hunting for the objects that will win them a super special prize. Nory is super excited for the scavenger hunt. Not only because she likes winning, but also because if her team wins, she thinks there's a chance her best friend Elliott won't move away to attend super snobby Sage Academy. Sebastian is a little less excited once the hunt is on. Yes, he has magical powers that help his team — like being able to see invisible things or anything that makes a sound. The problem is that the really loud sounds are hurting him . . . and nobody seems to care. The kids in Upside-Down Magic know their five F's (Flares, Flyers, Fuzzies, Flickers, and Fluxers) — but to win this night, a sixth F is the most important . . . Friendship.
