The Probability of Forward

A girl overlooked by most of the school population, Hadley Fang is a self-prescribed introvert. The person who has kept her grounded for the past 2 years is her friend Isabelle LeBrun, the only one who knows what makes Hadley want to hide away at every social event or interaction. But when Isabelle is ripped out of Hadley's life without preamble, Hadley is left without a best friend and someone who can encourage her to battle the struggle of social life day after day.

Until Aron Harker, one of the school's most infamous senior boys (a.k.a. Hadley's uncooperative calculus tutee), starts seeing her. And try as she might, Hadley cannot run away from him.

This is the story of a girl who runs because of and away from her social anxiety, and the person who teaches her how to step forward instead of away.
