Set in the year 2075, ten-year-old Iris’s quiet world is upended when she witnesses a boy in a radiant rainbow suit fall from the sky. His name is Arco, and he comes from a distant, seemingly perfect future where time travel exists — and where he is no longer safe. As the two children form a fast and heartfelt bond, Iris is drawn into an extraordinary journey across time, danger, and imagination. Together, they must outwit unseen forces and navigate unfamiliar realities to return Arco to his home, discovering along the way that friendship, courage, and hope can transcend even the boundaries of time itself.
