I'm currently reading it and really like it so far. It provides a really good history on interest rates all the way back from Mesopotamia. I like it because it's not another "why bitcoin is better money" kind of book. No mention of bitcoin or anything like that, but it's clear why we are on the right path with bitcoin and scary times are ahead for everything else. I like to read stuff that's outside our little BTC echo chamber, and this is one of them.
