I've read all of the main books of the Old Mans war by Scalzi. I really like Scalzi's works, with a few minor exceptions, and those mostly because they seem derivative and not Scalzi in all his glory. So, when the Human Division came out, even in its serialized format, I devoured it. The serialized format was torturous in the slow release, but awesome in the suspense that it built. The End of All Things was released in the serialized format, but, for some reason, all my new author alerts missed them. It wasn't until Luke mentioned starting it that I remembered I even had the book, auto-purchased on in Kindle format.
Shock. Reading a book this year that wasn't chosen by my mother? Amazing.
So, I picked it up and, unlike my reading for most of this month, zipped though it. I even read the alternate version, which I have to say, kinda bit. I'm glad that Scalzi listened to himself and chose the version he published.
It's a great conclusion to the Old Man's War series, in the same way the Lost Colony was a great conclusion, which is to say, if Scalzi wants to keep writing books in this universe, he can.
In this book we see many of the same characters from previous books in the series. I don't know how Luke read this book without having read the previous four (no, Zoe's Tale does not count), but he said it worked for him.
This series is recommended, this book in series is recommended. I recognize I will read pretty much anything Scalzi writes, and I am not ashamed to say this.
