Unfortunately I just did not like this book.
There's nothing I found glaringly wrong with it but I can't really tell you anything amazing about it either?
I am disappointed because I expected a premise that involves 75-year-old men and women raging an intergalactic war against a multitude of alien species to be wonderful and hilarious.
I imagined arming bitter, old grandparents, who curse loudly at the dinner table & rail on endlessly about the entitlement of the younger generations, with a renewed sense of purpose & enough high-tech firepower to blast E.T. into the next life.
That isn't what I got here.
To say that my expectations were not met is a bit of an understatement.
This is not a tale of Earth sending waves of savage senior citizens into the stars to defend their home planet. I should've realized what I was in for when I came across the following quote inside the book:
"The universe isn't going to be conquered by legions of geriatrics..."
What I did get from this book was some decent humor. And that's about it.
There is a strange juxtaposition between humor and brutality here that didn't necessarily work for me.
I guess when I read a Science Fiction book, I don't expect the most interesting parts to be the multiple, creative ways in which different alien species inflict death upon their enemies.
This, coupled with a rather boring plot & characters I couldn't feel connected to at all left me with little to praise.
Around the 90% mark I felt an overwhelming apathy to see the book through. Painfully, I did finish it. I may give Scalzi another shot later, but I won't be continuing on with the next book in this series.
