NINA AND THE KEEPER OF THE KEYSTONE

This second series entry finds the sixth grader, who’s happiest coding and tinkering with robots, staying safely behind the scenes, even though her friends on the Robotics Competition Team want her to take on a leadership role. She’s volunteering at her favorite toy store, a small local business that’s in danger of closing. She’s also dealing with her parents’ conflicts—Mama and Mum have been fighting. Using a magical keystone that allows her and her friends to connect to well-known women from the past through letters placed in a mysterious mailbox in the forest, Nina, who’s cued Black, and her racially diverse group of friends secretly help their classmates at Ada Lovelace Middle School solve their problems. When new superintendent Mr. Graves starts changing things about her school—and most definitely not for the better—Nina has to prove to herself that she can indeed be a Rebel Girl when needed. The story moves along quickly, and the cast members, all with distinct personalities, keep things entertaining and refreshing. Dumas skillfully intertwines and balances STEM and magic. Beneath the fast-moving adventure lies a resonant message about standing up for yourself, owning your mistakes, and finding courage when it matters most.
