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.
