Exhaustive analysis of the mess we are in, near everywhere in the world. In places it felt a bit rushed for a publishing deadline, & there is a lot of verbatim lifting from other works. But it is a good synopsis of the debt-burdened present, & it does, in a relatively balanced manner, seek to set out how things might pan out (deflation &/or inflation or elements of bad deflation combined with currency collapse). A cheery read it is not. And it is not a book holding out hope for, or indeed even considering, some sort of Sino-US-German agreed 'recalibration'.
I liked the country by country breakdown & assessment of relative ugliness, although there is, some would say not unreasonably, quite a lot of hedging in the analysis - Australia ready for bubble (actually they are very clear on that one), UK doomed but for having a lot of long term debt & not being locked into the German currency zone (so very high inflation looming), Japan doomed (so short the Yen & JGB, oh wait that's been the story my whole adult life & it hasn't worked), emerging markets going to be the place to be (but is that right given many are producers/commodity plays & in a crisis it will be 'go $') & US could go either way & might even muddle through because the producers have to vendor finance the US consumer. All good practical stuff in these parts of the book.
Overall, I did not find the book a 'wow', in that the de- versus in-flation debate in the face of global debt & inbalances versus 'don't fight the Fed' is well established but I did feel this book was perhaps slightly closer to the heartbeat of what is going on than Shilling's similarly-themed but differently-concluded book (The Age of Deleveraging).
Perhaps it is being unfair as it is a difficult question, but the book did not really get me any further to a resolution of the question of whether to be in cash because of deflation or in real assets because of inflation or as to what currencies might be the place to be etc. Perhaps this is because everything is in the balance & you need to be 50% in cash spread across, say, US$, Norwegian Krona, Canadian $, HK$ & Swiss Francs & 50% in an income-producing globally diversified equities ETF (either coming in on dips/after a more than 10% fall &/or drip feeding in), but it would have been good to have had the very short investment ideas chapter home in on this sort of practical consideration (which could also usefully have dealt with whether it really is safe, given the theme of the book, to be invested in any government securities, & whether gold etc are in fact good places to be).
Still, a good read, it is not a book drowning in technical data & it is all clearly articulated. So, I would recommend it.
