Y'know how you can learn a lot more about america by readying, I don't know, Tom Robbins's cartoon characters, or Aimee Bender's, than you probably would from John Grisham's ostensibly realistic ones? I feel like Vietnam through Linh Dinh's wide-eyed, opinionated, kind of aggro characters taught me more about Vietnam than I've ever learned anywhere else from anyone. I guess his affection level toward his characters is closer to Robbins's than ol Chuck P's, too, which is nice- more 'I live in a loopy time and place so I'm kind of loopy' than 'everything is totally hopeless, man.' (Although- edit- Linh Dinh doesn't really write like Tom Robbins at all.)
Did you know that this never came out in paperback? Interesting. Anyway, I recommend you read it. It's hard to talk about. Also, you will feel smart when you figure out what the opening picture is and what it means, which is nice.
