Like most 12-year-olds in 1979, Janet Bauer lives for Friday nights at the Moonlight Rollerway. This particular Friday is special - it's the last one before junior high starts. When Janet finds out the 8th grade girls have chosen her to be the 7th grade "runt," she decides she must skate with a boy to prove her maturity and avoid this fate, which would ruin her life forever.
