Love is a Revolution by Renée Watson
From Bloomsbury YA:
From New York Times bestselling and award-winning author Renée Watson comes a love story about not only a romantic relationship but how a girl finds herself and falls in love with who she really is.
When Nala Robertson reluctantly agrees to attend an open mic night for her cousin-sister-friend Imani's birthday, she finds herself falling in instant love with Tye Brown, the MC. He's perfect, except . . . Tye is an activist and is spending the summer putting on events for the community when Nala would rather watch movies and try out the new seasonal flavors at the local creamery. In order to impress Tye, Nala tells a few tiny lies to have enough in common with him. As they spend more time together, sharing more of themselves, some of those lies get harder to keep up. As Nala falls deeper into keeping up her lies and into love, she'll learn all the ways love is hard, and how self-love is revolutionary.
In Love Is a Revolution, plus size girls are beautiful and get the attention of the hot guys, the popular girl clique is not shallow but has strong convictions and substance, and the ultimate love story is not only about romance but about how to show radical love to the people in your life, including to yourself.
