Sapiens: A Brief History of Humankind

In hindsight, this book is so deceivingly simple that you are swept away in its prose - but you later realize that Harari's arguments either do not make sense at all or even if they sometimes do, they are not backed up with data. I'd rather read Piketty or Ferguson, who make for dry reading, but at the very least, they try to back up their opinions with fact.
