During a street interview, the interviewer asks, "What's the craziest thing you did in high school?"
Sophie's best friend, Juniper Young, shyly admits that she secretly changed someone's college applications so they could attend the same college. Then Sophie's childhood sweetheart and boyfriend, Flynn Sadler, casually reveals that he deliberately left the last question on his math exam blank so the person changing his applications wouldn't feel guilty.
Listening to them laugh together, Sophie finally understands what she has refused to see for years.
She spent her entire childhood chasing Flynn, abandoning her passion for art and working desperately to become someone worthy of standing beside him. Yet when it mattered most, Flynn was willing to abandon his lifelong dreams for Juniper without hesitation.
Neither Flynn nor Juniper realizes that Sophie has done something crazy too.
She has secretly applied to her dream university abroad—and she has been accepted.
After one final betrayal destroys what remains of her feelings for Flynn, Sophie leaves the country with her parents, changes her number, and disappears from their lives.
Only when Flynn arrives at Sophie's empty house does he finally realize that the quiet girl who always followed behind them isn't coming back.
This time, Sophie has chosen her own future.
And while she begins a new life thousands of miles away, Flynn and Juniper are left behind to discover exactly what they lost.
