The Upside of Down

A few posts ago, I wrote (of Cullen Murphy's Are We Rome?):

If you're looking for something a bit more substantial in your Americo-Roman comparisons, there's more substance in another book out there -- something I'll return to in a later post.

Well, the book in question is Thomas Homer-Dixon's The Upside of Down, and my review of it is now up at Gristmill. I can honestly say that this is one of my new favourite books. I would certainly rank it up there with Guns, Germs and Steel in terms of horizon-expanding works.

Check it out.
