The End of All Things is aptly named because the last 2 books of this series absolutely ruined it. The books were good and enjoyable but just dragged the series down because it had nothing to do with the original 4. OK, it did, in a way but not the way I was wanting. This like the 5th book, The Human Division was made up mostly of short stories that only had maybe 4 or 5 stories that could have been connected and had a far better outcome for me, anyway. Me, the armchair writer and storyteller that can sometimes have a rough time putting a sentence together in conversation, not counting writing.
Scalzi basically admitted that he had a lot of material left over after writing The Old Man's War series so he put these into two different books. I did say I enjoyed them but I love to read series and these last two were not series material for me.
As an armchair writer and storyteller, or call me a Monday morning quarterback, I would have made this a different series, just the same universe as The Old Man's War. But hey, I'm not John Scalzi. He makes a living writing. I don't.
The End of All Things are stories of an unrecognized group of races called the Equilibrium, a never heard of secret consortium of races and planets that wanted to end the two most powerful governments in the known universe, the Colonial Union, which is made up of the human race with the exception of Earth and the Conclave, an alliance of 412 races that's technology far exceeds earth. The CU and the Conclave have always been at war and with the unknown Equilibrium always trying to stir up trouble between the 2, peace will never happen. These last two books are about all the worries and woes, politics and battles, and unsuccessful attempts at peace.
