This is an exploration of what define consciousness. A small crew of clones has been sent into space and been given the challenge to create a conscious entity.

Most of the book is taken up with philosophical dialogue between the various characters. While the dialogue is interesting from a philosophical point of view, it's fairly stilted. The characters are one-dimensional and not very believable and there is virtually no character development. Perhaps this because the characters are clones who have been conditioned to behave in prescribed ways. (In fairness, many of them are aware of and try to overcome this conditioning, but without success).

In the end, the characters are little more than a way of exploring different viewpoints about what constitutes consciousness.

While I certainly found the discussions interesting, I wouldn't say that I actually enjoyed the book.
