What books or documents do you recommend to understand what makes bitcoin unique?

I've been involved in crypto for three years and I've always heard that the more you read about Bitcoin and understand how it works, the more you want to buy and HODL. So today I was curious to read and understand more so I hope for your help. I am studying economics so I understand the unique characteristics of BTC. However, I would like to understand more about its technology and the network.
