NEVER LET ME GO: Does the novel take a moral or ethical position on cloning, or does it just open a dialog?

I think the only moral or ethical positions I found came from my own personal reflections. The book itself presents the facts and the characters, and I think we are left to make our own decision based on their relationships, opinions and feelings.

It's a tricky one, but I think there is very little in the way of a biased viewpoint.

Thanks for asking an interesting question!
