Just blew through the entire (so far) 10-book Destroyermen series by Taylor Anderson. Took 12 days. Wow. That's good stuff. It's alternate-universe/military
And I just now finished re-reading Andy Weir's The Martian, which was every bit as good the second time around. Can't wait to see the movie. Looks like they stuck pretty close to the actual story. Well, they at least used a few of the words from the book, anyway.
I hope Andy Weir's check was BIG.
