The book is set in "Satan's Hearse" and Gutshot Tennessee. "Satan's Hearse" is the nickname for Colin's (the main protagonist) and Hassan's car that they use to go on a road trip to Tennessee, where they find the grave of the Archduke.

Colin is a "former genius" and has dated nineteen girls by the name Katherine. While on the road trip with Hassan, Colin meets a girl named Lindsey and they end up dating after connecting with each other.

The theme of this book is moving on to the future because Colin needed to move on from Katherine XIX and from his old ways of doing things. When Colin and Lindsey got together, Colin tried to create an equation based on past relationships, he predicted that Lindsey would break it off in four days. After four days, he found that his theory, which he has had with most of the nineteen Katherines, didn't hold true with Lindsey, he finally realizes that he can't use a science equation to figure out his love life.

I would give this book a five star rating because it has marvelous humor as well as deep meaning, very much like his other books. I would recommend this book to people that don't mind swearing; maybe early teens (13 years) and up.
