"The plot is compelling and fast paced, with nonstop adventure....An entertaining sci-fi romp with grounded, real-world tween struggles."-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.
