Reviews

This simple but effective introduction to portions of the electromagnetic spectrum is physicist Lightman’s second science-inspired book for children. As in Ada and the Galaxies (2022), co-written by Olga Pastuchiv and illustrated by Susanna Chapman, he emphasizes the wonders that science can reveal, nicely ending his narrative with Isabel wondering about other invisible things. . . . Invisibly and effectively instructive.

Softly rendered digital art not only sets a playful tone but offers plenty of hints about light and prisms to find before and after reading, from streaming sunlight to stained-glass windows to rainbows in confetti, cakes, and Isabel’s birthday posters. . . . A charming, breezy introduction to STEM basics.
