Vivian McMillan is a 16-year-old lesbian from New York City. Unfortunately, her dad was a firefighter who got a respiratory infection due to 9/11, which means both of them have to move out into the suburbs with her maternal aunt, away from Vivian's girlfriend Aster. The move also drives Vivian back into the closet, with only new friend Archibald, a young African-American artist interested in comic books, aware that she is gay, and that only because he guessed. This causes tension with both Aster and Vivian's childhood friend Sophie, who doesn't like it that Viv's been hiding things from her...
