I do not get to read as much as I would like. I don't get to read at work (ironically) and when I get home I have parental and spousal duties which leave me with little free time. And then I'm usually to tired for serious reading. So the reading I do get around to is often articles, blogs or forum threads. All reading that I enjoy but I don't read the novels or non-fiction books I want to read.
So I am very happy that I ran across Old Man's War by John Scalzi. The tag line is:
"John Perry did two things on his 75th birthday. First he visited his wife's grave. Then he joined the army."
I haven't finished the novel (to top everything off, I am a slow reader) but I am very much enjoying it. If you like military science-fiction along the lines of the novels Starship Troopers or The Forever War I think you would enjoy this book. It borrows a bit from each but is definitely its own book.
