Delinquent Magic — M.W. Fowler

Wanna buy some magic? Delinquent spells, potions, jinxes...Kasbalt High School has a magic problem. Its newest student, Charlotte Caster, swiftly learns that attending a school of magic isn't as fun as riding brooms and smacking baby trolls. Seeing the ghost of a missing former student and becoming friends with the dueling team's batty star members is nerve-racking enough without worrying about the black gourds, lessons, annual bonfire, and Halloween dance. Charlotte just wants to get through the year without being cursed.
