I really loved the Old Man's War series and bought them all. Agent to the Stars was good too. This one . . . The story was fine and Scalzi can certainly write, BUT there were just too many really graphic gory bits I found too disturbing. I should write more to give this a possibility of getting some attention, but am just to conflicted about the whole thing unfortunately.
Just BEWARE if you don't have a really strong stomach for things like . . .
Graphic descriptions of people and animals being beaten to a pulp.
Graphic descriptions of torture.
Graphic descriptions of people being killed.
Graphic descriptions of people being eaten by another sentient beings.
You get the picture.
If you aren't bothered by things like that it is a good book.
