Wow. 
 I've read a lot of incredible books in my time, but this stands out as one of the best. 
 To dissect it by plot or craft would cheapen the experience, in my opinion. 
 All I can say is that I'll never forget it, and that Shriver moved me in numerous ways--in horror, in revulsion, in sympathy, in grief, in understanding. If the ultimate goal for a writer is to make her readers FEEL, Shriver is unbelievably successful. 
 The one thing this novel never lets you feel is comfortable. This is a very uncomfortable story that needs to be told. And therein lies its beauty. 
 I recommend reading it without exposing yourself to plot-by-plot reviews or even the back cover. Go into it blind, and let Shriver tell you the story the way she intended it to be told.
