One young woman’s relentless quest to become the first Cherokee astronaut will irrevocably alter the fates of the people she loves most in this tour de force of a debut about ambition, belonging, and family.

Steph Harper is on the run. When she was five, her mother fled an abusive husband—with Steph and her younger sister in tow—to Cherokee Nation, where she hoped they might finally belong. In response, Steph sets her sights as far away from Oklahoma as she can get, vowing that she will let nothing get in the way of pursuing the rigorous physical and academic training she knows she will need to be accepted by NASA, and ultimately, to go to the moon.

Spanning three decades and several continents, To the Moon and Back encompasses Steph’s turbulent journey, along with the multifaceted and intertwined lives of the three women closest to her: her sister Kayla, an artist who goes on to become an Indigenous social media influencer, and whose determination to appear good takes her life to unexpected places; Steph’s college girlfriend Della Owens, who strives to reclaim her identity as an adult after being removed from her Cherokee family through a challenge to the Indian Child Welfare Act; and Hannah, Steph and Kayla’s mother, who has held up her family’s tribal history as a beacon of inspiration to her children, all the while keeping her own past a secret.
