Book excerpt: It's the summer of 1963 and JJ Green is a born songwriter - which is a major problem, considering that her family considers the music business to be a cesspool of lowlifes and hustlers. Defying all the naysayers, JJ takes an internship at the Brill Building, the epicentre of a new sound that is rapidly changing the world: rock and roll. JJ is finally living her dream. She even finds herself a writing partner in Luke Silver, a boy with mesmerising green eyes who seems to connect instantly with her music.
