A charming and funny space-based story about the power of friendship and memory, perfect for fans of Oliver Jeffers, Tiny T. Rex and the Impossible Hug, and The Invisible String, from the senior correspondent at WNYC's Peabody Award-winning podcast and radio program Radiolab. There once was a little black hole who loved her universe, and especially her friends: the stars and the planets, the space rocks and the space fox, even the flying astronauts. She loved to play and laugh with them as they soared through the galaxy. That is, until they disappeared—which was always what happened. The little black hole felt all alone. But when she meets a big black hole and shares her worries, the big black hole knows just how to help! And the little black hole finds out that she has the power to find her friends, wherever she goes. With a quirky, playful story and sweet and silly art, this heartwarming story reminds us all that, no matter how lonely or anxious we might get, friendship is never more than a quick thought—and glow—away. And with back matter that gives readers information about the real science of black holes, this is a perfect book for all of the young space and science fans out there!
