Below are some of my all time favorite books, both fiction and non-fiction.
Fingerprints of the Gods, by Graham Hancock.

Fingerprints of the Gods is a non-fiction book about our pre-history as humans on earth, but even that description doesn’t do it justice.
It’s a life-changing book. There’s my life before I read it, and my life after, it was that much of a watershed read.
Here’s Amazon’s write-up:

I’ve gifted dozens of copies of this book over the years and cannot recommend it highly enough. If you click the link above (or here) it will take you right to the Amazon link for it, though I’m fairly certain it’s available in most good sized bookstores.
In short, it makes you realize: 1. How much we don’t know. 2. How much we’ve been lied to. Our history goes back much, much further than we’ve been led to believe, and our story is much more complex than we’ve been led to believe, and the evidence of it is in plain sight, once you learn to see it. I know, I know it’s sounds loony, but trust me, the guy brings receipts. He makes very reasoned arguments with all kinds of data to back it up.
Just read the opening few pages — the link takes you right to the Kindle version and you can download a sample with the opening pages for free — and it will give you a very good idea of what you are about to embark upon: an absolutely jaw-dropping, eye-opening, maddening experience into who we are as a people, how we came to be, and how much our history has been glossed over or just plain lied about. It’s a stunner of a book, truly.
Mr. Hancock has since gone on to write lots of other books in the decades since Fingerprints came out, and some of them are pretty wild, but this one stands as his classic and best selling. If you want to see his Netflix series (I found it slow…) you can do that here.
