Midnight in the City of the Carrion Kid by James G. Carlson
Checked this out on the strength of the cover art and synopsis. Let me just say, Jeff Strand's book blurb for this one is spot on -- it's fucking weird! But it's also well-written and entertaining. Not to mention the illustrations are awesome. Finished reading the book in two sittings, and now I am off to find other titles from this author.
