Old Man’s War by John Scalzi appears at first to be an updated version of Joe Haldeman’s Forever War, but the take on it is much different. Scalzi is an internet favorite due to his long running blog Whatever (if you’re not familiar with his blog, google bacon cat) and Old Man’s War was serialized on his blog before being picked up by a publisher. It’s a different look at intersteller war and the start of a series (that’s up to 4 books now).
