**A Stonewall Honor Book · A *New York Times* and Indie bestseller!** **“A bighearted, deeply vulnerable, love-bubbly tumble through self-discovery.” —Casey McQuiston, author of the #1 *New York Times *bestselling* I Kissed Shara Wheeler*** **With humor and insight, #1 *New York Time* s bestseller Becky Albertalli explores the nuances of sexuality, identity, and friendship in this timely new novel.** Imogen Scott may be hopelessly heterosexual, but she’s got the World’s Greatest Ally title locked down. 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. 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. Even if that means bending the truth, just a little. 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. 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. . . .
