The middle Cooper sister, Stevie, had never paid much attention to whatever drama was going on in Riverdale, or even in her family. Her life was "eat, sleep, breathe, gymnastics," and she wasn't going to waste her energy focusing on anything other than getting to the Olympics. Besides, she hadn't lived in Riverdale since she was ten, when she moved to New York to live and train with the best of the best.
She knew some things, of course, like that Polly had been dating Jason Blossom, that Betty had been in love with Archie Andrews since she was eight, and that her parents were both just as terrible, self-righteous, and controlling as they'd been when she'd left, but that was pretty much it.
But when a broken wrist takes her out of gymnastics for at least a few months, Stevie finds herself having to trade her gymnastics-oriented boarding school for Riverdale High. She was far from excited, but she told herself that she could handle it - after all, she was Stevie Fucking Cooper, National Team Captain and national gymnastics champion, not the quiet ten year old who'd last lived there. But with Polly gone, her parents acting more suspicious than ever, and Jason Blossom's body turning up with a bullet hole in the skull, she realizes that she may be in over her head.
