The kind of book that bothers some people because the author's efforts are so constant and obvious, but wonderful. I still marvel at Amis's ability to write an entire novel backwards. But I also appreciate his ability to keep the book manageable. It's a book you need to learn to read and once you "get" the language, you don't want to stop. Brilliant.
Added: I recently re-read this book and it didn't hook itself into my brain like the last times. I'm not sure if I've gotten past the ideas and can't really appreciate it for anything else (the style and ideas are fantastic, but once those have been absorbed, there's not much else).
