Twins: A Graphic Novel (Twins #1‪)‬

Coretta Scott King Honor author Varian Johnson teams up with rising cartoonist Shannon Wright for a delightful middle-grade graphic novel!
Maureen and Francine Carter are twins and best friends. They participate in the same clubs, enjoy the same foods, and are partners on all their school projects. But just before the girls start sixth grade, Francine becomes Fran -- a girl who wants to join the chorus, run for class president, and dress in fashionable outfits that set her apart from Maureen. A girl who seems happy to share only two classes with her sister!

Maureen and Francine are growing apart and there's nothing Maureen can do to stop it. Are sisters really forever? Or will middle school change things for good?
