The summer after graduation, high school besties in New York City play an epic game.Cassie Donato and her three best friends have big plans to live it up before setting off on their post–high school lives. But while the London-bound Latine musician Nico, body-positive Asian artist Marcy, and Aaron, who's Black and headed to Harvard, all seem certain of who they are and where they're going, Cassie, who reads white, is taking a gap year to work at her family's diner, and she isn't so sure what she wants. All she knows is that this is the last chance for their friend group to be together before everything changes. But as the weeks pass, she's disappointed that the others seem too busy to make the most of this summer. Her solution? A revival of Risky Slips, their favorite childhood game during which players take turns on increasingly risky dares. They have 24 hours to complete them or forfeit. But as the friends compete, the stakes get higher and unspoken tensions rise to the surface, testing their friendships and future. Porretta's debut is narrated through speech bubbles and color-coded texts, and it captures Generation Z in all their exuberance and acceptance as well as anxiety. Despite a last-minute romantic twist that feels out of step with the work as a whole, the themes of embracing and growing with change prevail. The attractive, jewel-toned art dynamically conveys the urban setting.Light and refreshing fare. (Graphic fiction. 15-18)
