For me it’s definitely a book that often doesn’t get much love: Spin by Robert Charles Wilson. I read that book like ten times by now in both English and my mother tongue. Such a defining book for me since I first read it in my youth and it gave me a lot of food for thought regarding what it means to live a meaningful life. It is not really hardcore sci-fi after all but more a kind of coming-of-age novel that happens to take place in a sci-fi setting.

I like it for a quick overview. You just need to be aware that you have to check to full article if you find the summary interesting and really wanna save that information in your brain or do something with it.

Beautiful edit.
