"It's a boys-versus-girls battle! Big bully Andrew is determined to prove that boys are better than girls -- after all, boys are cool and totally rule. But Cassidy and Nina know that he's wrong, since girls smell sweet and can't be beat. But when classroom ghosts join the competition, the rest of the school realizes that something's not right. A ghost fight? not that's scary! The competition is on -- may the best ghoul win!"--Backcover.
