In the days following the disastrous Battle of the Bands, Adagio, with the help of her sisters and the one girl she hates the most, learns to cope with her failure.
Everyone has secrets. Sometimes they tell people about them, sometimes they don't. Even after hundreds of years, there are still things Adagio hasn't told Sonata. When Sonata finds a book full of Adagio's secrets, she just can't resist reading it.
