I understand why this is a classic, but it wasn't a classic for me. At least not by the end of it. It was undeniably interesting both in narration and concept (war, time travel, etc.), but most of the time I was lost and/or didn't care. It started out strong for me when it was more war-focused. The sci-fi bits were just not something I was interested in this time around. Still, I'm glad I read it.
