The Story According to Goodreads
"High school senior Ashley Hannigan doesn't care about prom, but she's the exception. It's pretty much the only good thing at her urban Philadelphia high school, and everyone plans to make the most of it—especially Ash's best friend, Natalia, who's the head of the committee. Then the faculty advisor is busted for taking the prom money, and Ash suddenly finds herself roped into putting together a gala dance out of absolutely nada. But she has help—from her large and loving (if exasperating!) family, from Nat's eccentric grandmother, from her fellow classmates. And in putting the prom together, Ash learns that she has choices about her life after high school."
