The dazzling Ray illuminates how light works—part of the Science Pals series, including Drop: An Adventure through the Water Cycle and Puff: All About Air

Meet Ray. He's light! And he's been shining since time began. Wherever there's life on Earth, there's Ray, helping everything under the sun thrive. And Ray can really move—fast. Have you ever hurtled through space? Become a rainbow? Made food for plants? Ray has! With brilliant wit and sparkling one-liners, Ray introduces readers to a light show like no other. Filled with awe-inspiring artwork, funny asides, and a spotlight on kid-enticing facts, Ray invites us to bask in his warmth, as he illuminates our world.

"[A] refreshing combination of charm and solid fact [and] a high-wattage spotlight on our most important power source." —Kirkus

"[A] brilliant addition to the Science Pals series. . . . Every part of the book is packed with fascinating facts and tidbits. [Kids] will appreciate Moon's inviting approach. —Booklist
"[Emily Kate] Moon brings the same refreshing combination of charm and solid fact [to Ray] that animated her profiles of water (Drop) and air (Puff) . . . . In the vivid illustrations, bursts of light brighten deep seas and underground layers to demonstrate energy’s reach, storage, and continual flow, as well as the planetary surfaces, where light plays an essential role in making food for all. . . . A high-wattage spotlight on our most important power source." —Kirkus

"[A] brilliant addition to the Science Pals series. . . . The smiling faces, hand-lettered witty captions, and bright, cutesy illustrations will appeal to science-minded early readers. However, Moon doesn’t shy away from advanced scientific concepts . . . Every part of the book is packed with fascinating facts and tidbits of information; even the endpapers delve into the science behind light, fusion, sources of light, and energy sources on Earth. Kids with lots of questions about how things work will appreciate Moon's inviting approach. —Booklist

Praise for Drop: An Adventure through the Water Cycle, a Science Pals Book:

"A stand out from others of its type . . . Perfect for a science lesson read-aloud." —School Library Connection

“An endearing, conversational introduction to the water cycle.” —Publishers Weekly

Praise for Puff: All About Air, a Science Pals Book:

"Fresh and breezy.” —Kirkus
"Cheerful [and] easy to understand." —Booklist
