On the subject of unmentionable things
(Book)

"Phoebe Townsend is a rule follower . . . or so everyone thinks. She’s an A student who writes for her small-town school newspaper. But what no one knows is that Phoebe is also Pom—the anonymous teen who’s rewriting sex education on her blog and social media. Phoebe is not a pervert. No, really. Her unconventional hobby is just a research obsession. And sex should not be a secret. As long as Phoebe stays undercover, she’s sure she’ll fly through junior year unnoticed. . . . That is, until Pom goes viral, courtesy of mayoral candidate Lydia Brookhurst. The former beauty queen labels Phoebe’s work an 'assault on morality,' riling up her supporters and calling on Pom to reveal her identity. But Phoebe is not backing down. With her anonymity on the line, is it all worth the fight?" --book jacket
