This book takes the ethical dilemmas of the previous book in the Ender series and pushes it more into the abstract. It looks at many of the grey areas and talks about how manipulation of another being is also wrong, but to a certain degree. This is well exampled as the two viruses at the end, the first is understood and accepted by the aliens, but the second is forced upon an unknowing populous. Both of these seem right in the given context, but they are very differently implemented. I look forward to the next books. The metaphysics was a little odd, especially when the Peter and Valentine show up. I wasn’t expecting that, and it is a big grey area in itself. I think there will be a lot more about it in the next book since he talked about that in the post-word.
