I have historically not been a huge fiction reader. But as I've gotten older, and started branching off from the business books that kept me occupied for the first 20 years of my adulthood, I have started reading more of it. I'm currently slowly working through John D. MacDonald's series of Travis McGee books, but I had seen multiple times that people enjoyed the scientifically accurate Delta V so I decided to give it a try and really enjoyed it. A near future story of billionaires and asteroid mining, it gave me a new appreciation of the economic and environmental reasons we will want to eventually venture into deep space.
