It's been a while since I read [b:Old Man's War|51964|Old Man's War (Old Man's War, #1)|John Scalzi|https://d.gr-assets.com/books/1402867788s/51964.jpg|50700], and I didn't quite remember all the details of the previous book in this series. But it turned out it didn't matter because we start with a mostly fresh cast of characters and view points. John Perry does not make an appearance in this book. Jane Sagan however does. Later.

This book begins with Colonial Union finding out that there's a war being planned against humans. A war that might eradicate humanity completely. But when the investigators follow the clues that lead to the cause behind that war, they soon hit a road block. Thus Jared Dirac is born. A soldier in the Special Forces, also known as the Ghost Brigades. This book deals with the Frankensteinian "monsters" humanity has created to fight the dirtiest of fights for them, to do what humans can't or won't do. Except, they aren't - monsters that is. And when you think it couldn't get any weirder, you get to meet the Obin.

This book has it all: military, space opera, strange aliens, and cool gadgets. Add the politics, intrigue, and philosophical issues, you're in for a great ride that you don't want to end. But end it does in a furious finale with interesting consquences that neatly set up the next book in the series. This is Scalzi at his finest.
