But these novels are a bit more…adult than she was prepared for. Between euphemisms like fresh dewy grass and pork stew, crushing on the boy next door, and knowing you want to do that one thing before you die–discovering your budding sexuality is no easy feat! As if puberty wasn’t awkward enough, the club consists of a brooding writer, the prettiest girl in school, an agreeable comrade, and an outspoken prude. Fumbling over their own discomforts, these five teens get thrown into chaos over three little letters: S…E…X…!
