Nina and the Keeper of the Keystone

Now that the Three Musketeers (and Kai) are best friends again, this is going to be the best year ever! But Nina’s friends all seem to want her to take charge when all she wants to do is blend in. And on top of all that pressure, she’s keeping two fluffy little secrets from her moms... When the school’s new superintendent ignores what the kids want, bringing in uniforms, shutting down clubs, and getting the best teachers in trouble, it’s time for action! Luckily Nina and her friends can turn to the mysterious mailbox for answers, and soon they have Ruth Bader Ginsburg’s advice in hand. Will it be enough to save Ada Lovelace Midde School and Ms. Jupiter? And will Nina finally feel ready to be a leader?
