I loved this book the first time I read it, but on the re-read I was less impressed. It made me realize I guess that it actually functions very much like a thriller/detective story, and thus once you know what the mystery is, it is much less interesting. I also found it extremely depressing that SPOILER ALERT the clones don’t even consider fighting against their destiny – to have their organs slowly harvested. Why is that? What is the message? That we all are so deeply trapped in our worldview we can’t ever throw it off for any reason? I don’t know, maybe that’s true, but damn.
