Writing sequels is hard, I get that. Especially when your first book is something as awesome as "Old Man's War." But I just didn't enjoy this one as much. Not that I didn't like it at all, far from it, but it just wasn't quite as enjoyable as the first.
We've left John behind to follow the Ghost Brigades, specifically one particular and special one. He raises a whole heck of ethical problems in his 'birth' which are very interesting and we get to see more of the world outside of what we got in the first one. Maybe I just didn't click with the characters as much this time. Or maybe just not the right ones. But it's overall still a fast paced book with a wonderful amount of humour even in the moral quandaries and warzones.
