With humor and insight, #1 <i>New York Times</i> bestseller Becky Albertalli explores the nuances of sexuality, identity, and friendship. <br /><br />Imogen Scott may be hopelessly heterosexual, but she’s got the World’s Greatest Ally title locked down.<br /><br />She's never missed a Pride Alliance meeting. She knows more about queer media discourse than her very queer little sister. She even has two queer best friends. There's Gretchen, a fellow high school senior, who helps keep Imogen's biases in check. And then there's Lili—newly out and newly thriving with a cool new squad of queer college friends.<br /><br />Imogen's thrilled for Lili. Any ally would be. And now that she's finally visiting Lili on campus, she's bringing her ally A game. Any support Lili needs, Imogen's all in.<br /><br />Even if that means bending the truth, just a little.<br /><br />Like when Lili drops a tiny queer bombshell: she's told all her college friends that Imogen and Lili used to date. And none of them know that Imogen is a raging hetero—not even Lili’s best friend, Tessa.<br /><br />Of course, the more time Imogen spends with chaotic, freckle-faced Tessa, the more she starts to wonder if her truth was ever all that straight to begin with. . .
