There’s only one gift Isabel wants for her sixth birthday: a way to see invisible things. She can hardly think of anything else! Finally, the day of her party arrives. Unwrapping a big box, Isabel finds a surprise inside—a glass prism—and a dazzling world of previously invisible color emerges, lighting up the room around her. What else could be out there, waiting for her eyes to discover? In simple, engaging language, complemented by luminous artwork from best-selling illustrator Ramona Kaulitzki, author and physicist Alan Lightman unveils the hidden world of light waves—the ones you can see and the ones you can’t. Back matter delves briefly into the subject of wavelengths, radio waves, and X-rays for readers curious to know more.
