Hailey McEwan has many interests—soccer, field hockey, animation. She'd probably never have started singing if her best friend, Crissy, hadn't persuaded her to take singing lessons and join her choir. No one had any idea that Hailey would be such a natural, least of all Hailey herself. A shared love of music—from pop to opera—has been a big part of the girls' friendship, but when the two face off in a competition for a role in a production of The Marriage of Figaro, their closeness turns into a bitter rivalry. Hailey will have to make a tough decision. Is opera as important to her as it is to Crissy? And is landing a role worth losing her best friend?
