The Caveman's Valentine, by George Dawes Green

This one was tough to get through because I didn't like it.  My thought is that great literature needs to skillfully integrate plot, theme, character and style.  Here's my take on those four areas:

Plot:  The story is built around a murder mystery, but the main character trying to solve the case doesn't do much intelligent to solve it and basically stumbles across the solution.

Theme:  No theme is clearly demonstrated.  For a while I thought it was going to delve into how most people are content to go along with the world as other people have created it, but the story never went there except for a few rants from the main character.

Character:  The main character is a schizophrenic homeless man living in a cave.  The author has a tough assignment with this protagonist because he has to make the guy crazy enough to explain his homelessness but sane enough to solve a murder mystery.  The author didn't pull it off, in my opinion.

Style:  This may be what turned me off most:  many of the descriptions bordered on and went beyond comprehension.  I suppose this was to let us know what it was like to be in the mind of a schizophrenic, but it also smelled of avant-garde artsy crap like James Joyce.  Aside from these semi-coherent descriptions, the writing was okay but nothing special.
