School Library Journal
Aku has always dreamed of becoming an astronaut. It's easier to picture life among the stars than deal with the bully at school--or the pain of his grandfather's mysterious disappearance. But when a strange space helmet shows up in his basement, Aku is pulled into something far bigger than he ever imagined.
The space helmet doesn't just look cool--it teleports him to Ibra, a distant planet under siege. There, precious Lunaberries are being stolen by a ruthless space militia, and Aku's grandfather may be the key to stopping them. With the help of his best friends and a few unlikely allies, Aku must dream bigger than ever before, find the courage to lead, and discover that bravery isn't about having no fear--it's about rising above it.
