Going trough Seven Eves (or Seveneves if you will, even tho he former makes more sense after a certain point in the book). Pretty damn good hard sci-fi about the end of the world and how people are trying to survive it. The writing could be a bit better (mostly repeating already stated facts as if this is a series of different books so the author needs to explain certain concepts every time, or they think the average reader will forget these things by the time they're brough up again :S
Anyways, the second part of it is not as interesting from a character point but the tech stuff and some of the solutions are pretty damn neat and evoke feelings of old school sci-fi with it's sleek desings and novel solutions to certain problems, a certain air of Syd Mead about it all I guess, which is a pretty damn big boon.
Aside from that, tho I'm not sure if it can be considered reading since it's a podcast but I've read over twenty books in audiobook form in the past six months so I'll just sort them in the same box, these would be more like short essays on certain themes. In this case, it's the Lore series by Aaron Mahnke, he's a writer but I've never heard of him before today when I learned about the series and went to check it out. It basically trawls various myths over the world and talks about them, comparing them, singling out interesting stories and talking about what they could mean or represent to the people of the time. Pretty well researched and written, and episodes are about 20 mins long so not too much time to put away for one or two.
