I enjoyed OLD MAN'S WAR. It has a solid story, witty dialogue, interesting characters, and enough new twists and themes to invoke the old brain matter. In the beginning I thought it was going to be typical space war story, and although there are body exchanges and understandable rowdiness and soldiering, the introspection, friendship and love story added enough subplots to keep my interest. I loved the skip through various alien races.
The prose is well done, straight forward and easy reading. I especially loved the banter and insights of old folks in young military bodies. Well done, and recommend for sci-fi lovers who like some science, but not an overload.
