Like any normal sixteen year old, Lucy Karate longs for the perfect junior year. The petite brunette imagines herself having fun hanging out with friends, getting good grades, finally finding a boyfriend, and, above all, marching on The Battery. For Lucy, a member of the highly competitive Forrest Hills Flyers Marching Band, The Battery is a chance to actually march on the field and show everyone that girls really can be outstanding percussionists. Rewarded with second bass after intense tryouts, Lucy immediately finds herself in trouble when she begins secretly dating the rival school's Drum Line Captain, Sam Powell. At the same time, she finds it difficult to turn down the attentions of cymbal playing redheaded hottie, Nevada Petersen, from her own section. What's a girl to do? Woodwind or brass, color guard or majorette, you will want to follow Lucy's misadventures through marching band. Her struggles with chaotic band camp, cute rival drummers, intense indoor competitions, and a crazy love triangle will speak to the band geek in everyone.
