Gr 3--7--Phoebe and Marigold's friendship is sparklier than ever, though Marigold's sparkling family may have something to do with that. Across the mini-plots that occur through this latest set of four-panel punchlines, the two friends engage in the sort of gentle ribbing that is only possible over time. Establishing a clubhouse, doodling on class work, and reacting to internet opinions are all fodder for the pair's sharp wits and Marigold's magic powers. In the end, each topic circles back to the differences between humans and unicorns, which always leads to either a humorous or thoughtful reflection. Readers may find themselves looking for more information about computer pioneer Grace Hopper and U.S. President Rutherford B. Hayes afterward. A glossary in the back provides definitions for potentially unfamiliar vocabulary. VERDICT The series's central duo continue to share laughter, heartwarming friendship, and plenty new ideas for readers to think about. Best for familiar readers.
