it is a paperback with a blue cover with stars on it and a lady. i can't remember all the details but i think it was about a king who was in love with the night sky, once he was too sick to go outside and look at it, the queen or princess or something made a dress that looked like the sky and she wore it for him every night. when the king died she became the night sky or something like that. i'm obsessed with trying to find it. it's a picture book and it's pretty thin, maybe 20 to 30 pages at the most.
