How to Catch a Star by Oliver Jeffers (2004)
Once there was a boy, and that boy loved stars very much. So much so that he decided to catch one of his very own. But how? Waiting for them to grow tired from being up in the sky all night doesn't work. Climbing to the top of the tallest tree? No, not tall enough. The boy has a rocket ship . . . but it is made of paper and doesn't fly well at all. Finally, just when the boy is ready to give up, he learns that sometimes things aren't where, or what, we expect them to be.
