Charles Xavier graduated from the Royal Academy of Music in London a virtual virtuoso, having received the London Music Rising Star Award and numerous other commendations for violin, piano, and composition--so no one expected him to end up conducting for an under-funded orchestra at a Chicago public high school. But Charles loves his job, and it keeps him close to his half-sister Raven, a freelance musician. When his beloved sibling needs violin sheet music for songs from the up-and-coming rock band Mutant Brotherhood in order to impress a prospective girlfriend, Charles is only happy to comply. However, he wasn't expecting to become hopelessly wrapped up in the band's affairs, and certainly not its moody and argumentative main vocalist.
In which classroom phone rules are broken, rock artists and water do not mix well, eardrums barely survive through senior year, sleazy managers cause problems, pining musicians write songs about one another, a guitar becomes a projectile, and maybe modern popular music isn't as entirely an abomination as Charles previously thought.
