Most of the science in this novel is bad, but one important thing that the writer got right and presented properly is that cloning is the absolute last desperate move you can make to save a species. Just as one might expect, the story turns into a conflict between an individual and the community, with plenty of counter culture sprinkled all over (am I the only one who noticed some stylistic similarities with The Silent Spring).
Even though bits of the story are predictable, I was taken in by the method and style the author used to tell it (probably because I am used to think of clones in a more cyberpunk setting). And this made it not the best read, but an enjoyable one.
