"The national competition is coming up fast, and Julie, Lucie, and Alia will need all their skills, all their poise, and a lot of grit and determination to get their routine in perfect shape. The always jealous, ever-scheming Carla is trying to sabotage everything again, but the girls are used to that; what they weren't expecting was their teacher, Mary, falling sick at the worst possible moment! As they struggle to choreograph something on their own for the first time, it may be up to Lucie to step up and save the day"-- from publisher's web site.
