I'll try anything once.
This book is much deeper than a story of an agent representing extraterrestrials. Scalzi writes a story about the Holocaust without ever having to dig terribly deep into the gruesome details. My only complaint is that the last half an hour or so is difficult to get through. This is not due to the subject matter but the fact that it is mostly composed entirely of news blurbs and clips. It does pick up again for the last ten minutes or so. In my opinion, it is a good and worthwhile read.
I remember reading a Kurt Vonnegut novel (Breakfast of Champions) and feeling like I had read something really special.
I didn't read this book (obviously) - but while listening to it I had that same kind of feeling. The story, the philosophy and, Oh the voice & range of the narrator caused that same kind of reaction.
I don't know if the print medium would have caused this feeling and have no plans to find out. (Sometimes I like the story, but not the narrator & return it so I can get the print version just to see.)
The comical ideas often found more in children's story's are used by the author but it is not written for children making it far more comical. Silly sarcastic aliens and humans offer some good laughs.
A funny story about human alien contact. The humour doesn't really get into gear till the talking dog appears.
Narration was good but I couldn't understand Wil Wheaton at x2 playback speed, had to drop it to X1.5.
Scalzi is a great writer and Wheaton gives an excellent performance.
There are no points where the story begins to drag. It is humorous but not fluffy. The story is good science fiction which entertains while getting you to think.
