Starr's family has been given the opportunity of a lifetime: To move to outer space! They'll live on the world's most advanced space station and help space tourists explore different planets. Starr is excited, curious, and terrified about the big change. She'll have to leave her school, her house, and worst of all, her best friend, Allison. But whatever happens, Starr knows her new life will be out of this world!
Moving is hard for any kid, but Starr is learning that moving to outer space is a whole new challenge―especially when you float in microgravity!
