Books by Kate Karyus Quinn
Piper Pájaro and Sloane MacBrute are two 13-year-old girls with very different lives but very similar secrets. Popular, outgoing Piper is strong. Like, ripping-the-doors-off-cards strong. She longs to be a superhero, even if she tends to leave massive messes in her wake. Snarky Sloane, on the other hand, is super smart. Like, evil-genius-smart. To help her family, she has to put those smarts to use for her villainous grandfather.
