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?! Here's what people (and robots!) are saying about Hilo! "Every kid would love a pal like Hilo, and every kid will LOVE this book!" --Lincoln Peirce, author of Big Nate series "More giant robotic ants and people going 'Aaaah!' than in the complete works of Jane Austen." --Neil Gaiman, author of Coraline
