When I first read this series, I didn’t think much of it, but after coming back to re-read it, I found I truly enjoyed this book and the Old Man’s War universe. I think part of my initial dislike was the brevity of the book. At under 10 hours is hardly compares to the massive tomes of Reynolds or Hamilton. I wanted more. John Scalzi write fun, sometimes funny, sci-fi with well-developed characters inside a massive galaxy of aliens.
