I appreciate what Shriver wants with this book: it describes the downfall of the US in a near future: the dollar becomes worthless, the economy collapses, etc. What follows is an exploration of possible outcomes of this downfall. The family Mandible is just a tool necessary to discuss the situation. But it didn‘t work in my opinion. Dystopian fiction is not the best choice, an essay would have been better although I probable wouldn‘t have read it
