Meet Scarlett Epstein, BNF (Big Name Fan) in her online community of fanfiction writers, world-class nobody at Melville High. Her best (read- only) IRL friends are Avery, a painfully shy and annoyingly attractive bookworm, and Ruth, her pot-smoking, possibly insane seventy-three-year-old neighbor.

When Scarlett's beloved TV show is canceled and her longtime crush, Gideon, is sucked out of her orbit and into the dark and distant world of Populars, Scarlett turns to the fanfic message boards for comfort. This time, though, her subjects aren't the swoon-worthy stars of her fave series-they're the real-life kids from her high school. Scarlett never considers what might happen if they were to find out what she truly thinks about them...until a dramatic series of events exposes a very different reality than Scarlett's stories, forever transforming her approach to relationships-both online and off.
