Read this a few years ago. It was completely weird but clever and, as far as I can tell, original. 
 It's set in a world where the wrong side of the tracks is home to clowns. One clown (Nita) is just trying to get by while her boyfriend is away at clown school. 
 It may be difficult to identify with the main character if you've never donned clown white and a red nose but if you have, I think you'll like this story. 
 Just remember one thing: this book is set in a fantasy world. Prepare for the absurd!
