In Greek mythology, there were nine muses, all of them daughters of Zeus. But the legends forgot the 10th Muse - the Muse of Justice. This is Emma Sonnet's birthright. In high school, everyone has their secrets. Emma Sonnet, popular cheerleader and debate team member, has a secret she can tell no one. When students on the swim team are missing, Emma (as the 10th Muse) must solve the puzzle of the Minotaur in time to save them.
