Ah like the 100 year old hyperloop idea he invented and dropped because it was a stupid idea? (that musk fans still think he is working on for some reason)

Howdy doodily doo neighbouriinos.

You might try gateway. First book of heechee by Frederick pohl. The science is a bit wacky (think 1960s people thinking we would be on the moon with lasers in space 1999) but there are themes of depression and mental health. I’m not sure if I could suggest the rest of the books, but gateway is pretty solid imo.

I’m in the middle of trying to make aspects of it into a mod for stellaris right now but I’m not a good writer so I’m procrastinating!
