I have had good luck with Booker prize winners but not with this one.  It is very annoying when the first few chapters demonstrate interesting writing and good potentials for the plots and then it just stops, not going anywhere. Nothing signficant happens until page 142, and even that is not very interesting at all.  Throughout the book, there is numerous unnecessary mentioning of sex, as if it is from one of SNL sketches where it gets mentioned randomly (remember one of the sketches with Tom Hanks where "penis" is said multiple times?).  I get that sex is relevant to this story, afterall, perpetual pregnant state of the protagonist's mother is a ubiquitous reminder of sex but in this case, just too random and feels almost too cheap.
