From the publisher

Book 2 in the electrifying middle-grade sci-fi trilogy by six-time Grammy Award-winning musician, Academy Award-winning filmmaker, and New York Times-bestselling author Ahmir “Questlove” Thompson and New York Times-bestselling author S. A. Cosby. On the heels of their thrilling appearance in Rhythm of Time, best friends Rahim and Kasia are back traveling through time in Time for a Change. Last time around, they were on their own–now they are working with Aevum, a mysterious organization from the future that tasks them with averting disaster and safeguarding the flow of history. The first assignment sends Rahim to Hawaii to recover a rock that Aevum insists is key to stabilizing the future. But things take a dramatic turn when he inadvertently jeopardizes the mission, thrusting him and Kasia into a web of intrigue populated by a diverse cast of time-travelers with their own enigmatic motives. There are doppelgängers from parallel dimensions. There are robots who may be allies but may be enemies. As Rahim and Kasia move like pinballs through time, they must navigate a treacherous path to unveil the truth and avert a devastating future across multiple realities. Dynamic, richly written characters, a mystery that twists and turns through the corridors of time and the multiverse, interior illustrations, and crisp prose make for an infinitely readable sci-fi adventure that is sure to delight young readers.
