My Year of Epic Rock by Andrea PyrosIf Life Was Like a Song

Nina Simmons’ song would be “You Can’t Always Eat What You Want.” (Peanut allergies, ugh). But that’s okay, because as her best friend Brianna always said, “We’re All in This Together.”

Until the first day of the seventh grade, when Brianna dumps her to be BFFs with the popular new girl. Left all alone, Nina is forced to socialize with “her own kind”–banished to the peanut-free table with the other allergy outcasts. As a joke, she tells her new pals they should form a rock band called EpiPens. (Get it?) Apparently, allergy sufferers don’t understand sarcasm, because the next thing Nina knows she’s the lead drummer.

Now Nina has to decide: adopt a picture-perfect pop personality to fit in with Bri and her new BFF or embrace her inner rocker and the spotlight. Well..

Call Me a Rock Star, Maybe.
