Per Amazon reviewers: While not much of a mystery, Nana is one of the better written Delacorta novels. This prequel was written after the "sequel" DIVA which probably should be read first. A sub-plot of the book tells the story of how Gorodish and Alba meet, and is worth reading just for that. Delacorta goes into a bit more detail and description in this novel than he does in most of his others.
