Linus is the new boy at school, and he’s trying to keep it quiet. After coming out as trans last year and managing the attention that came with it, he’s more than happy to fade into the background of his new middle school.

Etta isn’t like other kids at school, and she’s proud of it. The class misanthrope and the owner of the greenest hair at Doolittle Middle School, she's still reeling from a painful friendship breakup, making her more than happy to burn middle-school bridges before she heads off to the local alternative high school next year.

When Etta’s over-it-all attitude sparks a challenge from her ex-best friend, Marigold, to get Linus elected student body president, Linus is thrust back into the spotlight. But what started out as a bet quickly turns into a true friendship between Linus and Etta, one that could be in jeopardy if Linus finds out the real origins of his and Etta’s connection. Can Linus and Etta’s friendship withstand the betrayal of the bet?
