1. Lemonade Mouth-Mark Peter Hughes, which is the original novel before Disney channel Disney-tized it. It's actually quite good and has the real full version of the high school misfits making a strange sounding band.
2. The Madonnas of Echo Park-Brando Skyhorse, about a bunch of women in a Mexican American neighborhood in L.A. impersonating Madonna for an event but are interrupted by a girl being shot in their neighborhood.
3. The Flappers: Diva-Jill Larkin, the third book in the series about three girls in the 1920's who go to New York City to make it big and be successful during the Prohibition.
Read them! I guarantee you'll love at least one of them!
