Maya and her friends from coding club have an exciting new project: they're coding lights and music for the winter dance! But when Maya's old troublemaking friend Nicole moves to town, Maya starts spending a lot of time with her, and less time with her coding friends. Nicole just gets her in a way that her other friends don't.

Will Maya get swayed by Nicole's wayward ways, or will she stay true to her "permanent group" from coding club? And will she come through on her part for the light and music coding project? Maybe coding--like friendship--is about being there for your friends when they need you the most.

Perfect for fans of The Babysitters Club and anyone interested in computer science, this series is published in partnership with the organization Girls Who Code!
