Hello, Star. I know you're scared, but you're not alone. When a young girl learns that a bright light in the sky is coming from a dying star, she promises to keep it company until the light goes out.

Every night she reassures her friend that she's still there. As the years pass, the girl learns everything she can about planets, space, and the universe, inspired by her dimming friend - until she realises she needs to do something more. This touching tribute to stars, space, and science celebrates how a small act of compassion can flourish into a life full of meaning and wonder.
