I second the suggestion for Dreamchipper. Mercurial and Queen Euphoria are both incredible, and the story in them is filled with very strong themes. They can also get a bit dark, so up to you how your table handles that. However, in Mercurial they deal with the star herself a lot, whereas in Queen Euphoria they really don't.
Dreamchipper, btw, is a great intro to old-school, 80s-inspired Pink Mohawk style runs that still have a very clear ethical dilemma at the end. It's a damn good staple of the genre.
