What REALLY happened in Hilo’s world before he came to Earth? D.J. and our favorite space boy, Hilo, take a DANGEROUS trip to Hilo’s home planet to find out! But everything Hilo thinks he knows about his past is about to be turned inside out and UPSIDE DOWN! Hilo was supposed to save everyone…but what happens if it’s Hilo that needs saving?! Is ANYONE who we think they are? Can Hilo and his friends figure out how all the pieces fit…before it’s too late?!
