Blast off into a sci-fi adventure in this electrifying middle grade debut starring Aku—the groundbreaking 3D character who graced the cover of TIME Magazine.

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.

This thrilling first installment in the Aku series is a cosmic coming-of-age story perfect for fans of Amari and the Night Brothers and Tristan Strong.
