Idea

An old friend of the All Time Low guys from high school moves back to town after retiring from the navy and they give him a job working at their music shop. His daughter, Holly Forney, becomes best friends with all of their kids as they spend the summer together, and then begins her freshman year of high school.
This is her journal of the first year required by her English teacher to be able to look back on it later in her high school career and see where she's grown.
