Perfect for fans of The Babysitters Club and anyone interested in computer science, this book by New York Times bestselling author Stacia Deustch is published in partnership with the organization Girls Who Code

Sophia and her coding club BFs have the best time together. Sure, they work on coding projects, but mostly they gossip about crushes, eat cookies, and do totally silly impersonations. Now they're about to participate in their first hackathon--a full day of coding and meeting other coders--so it's time to step up their game

Just when Sophia and her friends think their hackathon project is ready for the big time, a change of plans threatens to tear their group apart. Will they have each other's backs, or are they destined for an epic fail? They know that coding is all about teamwork and problem-solving--maybe friendship is, too
