It's a graphic novel about a whiny artist who hangs out in cafes and goes to parties. Occasionally, something strange happens. It's pretty; some of the banter is witty; I'm glad I read it. The plot advances slowly, but it's a fun ride.
There's more than one comic book out there called "Chiaroscuro"--no doubt this is a hazard in the comic book industry, populated as it is by artists. "Hey, let's name the book after a term of art of art." How many romance comics are titled "Two-Point Perspective"? Uhm, hmm. Now that I look, I don't find any. So much for that theory.
