I'm reading Yuval Noah Harari's book named Sapiens. The book is pretty interesting but I wonder if there's a particular word for such a book. It's not a novel, or a biography/autobiography and nor is it a memoir.
Wikipedia categorises it under the genre of "Non-fiction" but, I feel non-fiction is too broad to describe it. It's more like a Nat-Geo documentary but I'm not sure if calling it a "documentary book" is a great idea or even correct for that matter.
So, I want to ask the native English speakers and Literature academics what would they call it.
