Straight, fun sci-fi adventures are hard to come by these days, and Scalzi has done an awesome job with this one, with great characters, plotting and dialogue wrapped up by a plot that always stays 10 steps ahead of the readers.
Neat. Congratulations also to my pals David Louis Edelman and Toby Buckell, whose books made this list as well.
Fun trivia fact: Bookgasm posted this list at 8:19 am; I found it at 8:24 and posted this a couple of minutes later. This is my ego search kung fu, and it is strong.
