One girl wants to be extraordinary. Another wants nothing more than to be an ordinary girl.

Kennedy is a people watcher, always measuring herself against the girls who seem brighter, happier, more alive. She’s drawn to the extraordinary, which is why she can’t look away from the girl in the periwinkle dress holding a sign that says she’s looking for girlfriends.

Cecile is a love song to femininity. She adores dresses, makeup, and the simple joys of girlhood she’s always dreamed of sharing with her friends. For Cecile, being an ordinary girl isn’t boring—it’s everything she’s ever wanted.

As their friendship deepens, Kennedy can’t understand why Cecile is so happy with ordinary sleepovers and shopping trips. What she doesn’t know is that Cecile’s joy didn’t come easily, or that the things Cecile writes about in her notebook every day—and the feelings she’s beginning to have for Kennedy—would force Kennedy to confront everything she believes about girlhood, femininity, and who gets to want friendship without having to earn it.

Because if Kennedy learns the truth, she may have to choose between holding onto her ideas about what makes a girl extraordinary—or holding onto Cecile.
