Let me recommend PKD to you. You can start anywhere in terms of what to read first, his library is vast. He’s has well over 200 novels and many short stories , enough to have 4-5 omnibus’ that are thick as a dictionary
But all that choice can be overwhelming; start with Ubik. I’ll post a link. I’m going to grab a copy soon myself for two reasons…it’s a great story that I need to reread…and if I remember correctly, it has a lot of strange parallels to Bitcoin.
