17-year-old Lennie Walker, bookworm and band geek, plays second clarinet and spends most of her time tucked safely in the shadow of her outgoing sister, Bailey. Their mother left when Lennie was one, and their sisterhood and the support of their wacky and loving Gran and perfectly Northern Californian hippie uncle has pulled them through. So when Bailey suddenly dies, Lennie crumples. At first, it seems the only person who truly understands the depth of her loss is Baileys ex-boyfriend, Toby. Their mutual grief turns into something that seems confusingly like romance. Then theres the nearly magical allure of Joe Fontaine, new boy in town and thrillingly talented musician, who is falling for Lennie as fast as shes falling for him. One boy is like the sun, the other the moon; one takes her out of her sorrow, the other comforts her in it. But Joes been hurt before, and when he walks in on Lennie and Toby, Lennie is forced to take responsibility for her actions. What she discovers is not just love, but the strength to admit to her dreams of Julliard, confront her anger towards her mother, and ultimately, claim her rightful position as first clarinet not just in the band, but in the crazy cacophony of her life.
