Ptolemy Bent--"Popo"--is different. At an age when most babies are cooing "Mama, " Popo was speaking in complete sentences. He was reading college textbooks when he was still too young for nursery school. Popo may just be the smartest human being on Earth. And he spends all his time listening to the radio . . . to white noise that comes drifting down from the sky like stardust. Chill Bent is a two-time loser with a hair-trigger temper. After the death of Popo's mother, the ex-con assumes responsibility for his nephew, vowing to protect the boy from a government eager to strip away his African-American heritage and exploit his genius like a natural resource. Together, Popo and Chill are about to embark on an extraordinary journey into the farthest reaches of the mind and the soul . . . a journey you will never forget.
