Book excerpt: Music is in Sammy’s blood. His grandfather was a jazz musician, and Sammy’s indie rock band could be huge one day—if they don’t self-destruct first. Winning the upcoming Battle of the Bands would justify all the band’s compromises and reassure Sammy that his life’s dream could become a reality. But practices are hard to schedule when Sammy’s grandfather is sick and getting worse, his mother is too busy to help either of them, and his best friend may want to be his girlfriend. When everything in Sammy’s life seems to be headed for major catastrophe, will his music be enough to keep him together?
