Jess, Celia, Nat, and Lucy are the Gamer Girls—four BFFs who game together. In this fourth book of the exciting series, the friends discover a new game at a local arcade, Dance Dance Rhythms. (Okay, maybe it's not that new. In fact, it's a little retro.) But mistakes happen and it's up to Jess to put them right, or else her mom's dreams could be CRUSHED. This is the fourth book in the popular Gamer Girls series, for fans of The Babysitter's Club AND Pokemon! Jess never thought she'd be a gamer. The posters in her bedroom are dedicated to Naomi Osaka and Misty Copeland, not video game streamers. But ever since joining the Gamer Girls squad, Jess has learned a TON about video games. One evening, Jess discovers something wonderful . . . sitting in her parents’ guest room is a brand-new, sealed Dance Dance Rhythms game from the ‘90s! What's more, if she trades it in at the local game store, she can get a NEW game. But trading it might not have been the best idea . . . and Jess might have to risk it all in order to get it back. Can Jess keep going at her fast pace, or will she need a new rhythm? In this fourth book of the popular Gamer Girls series, four friends navigate the video game world and the middle school world . . . if only they could solve drama as easily as they defeat monsters! Gamer Girls: Retro Rhythms celebrates history, family, Black Girl Magic, and the 10th anniversary of legalized queer and gay marriage in the United States (Jess has two moms). This series is perfect for readers who love video games. Retro Rhythms includes 30 black-and-white illustrations throughout.
