The first of a new series about two friends from Philadelphia who get in over their heads when Kasia gives Rahim a new cell phone she’s created for him. Best part: it’s free & off the grid, so no pesky monthly bills. Worst part: it sends Rahim back in time to the Philly of his Dad’s childhood causing increasing problems with the time/space continuum. I loved that Rahim gets to see a side of his father that is so different from what he thinks he knows about him. It introduces the idea of the butterfly effect in messing with time in a kid-friendly way. Both main characters are black and smart and talented.  Rahim is a budding musician who loves rhyming and making music even though his father just wants him to be academic. Kasia is a brilliant scientist-in-the-making who pushes the boundaries, perhaps a bit too far, but without giving up on finding a solution.  The book includes a few drawn illustrations that I didn’t feel were absolutely necessary, but will appeal to readers who need a little visual support. The plot moves along with plenty of excitement and complications, but doesn’t dwell overlong in solving the problem of getting Rahim home. Overall, you can bet it will be a book my students will enjoy and will be wanting the next in the series because, of course, there is a tiny teaser at the end.
