This was interesting. From the beginning, I had my money on Jenna being either a robot or a clone. Turns out I was both wrong and right. The mystery is revealed pretty quickly, and then the ethical dilemmas involved take over the rest of the book.

They were pretty wild ethical dilemmas, and both sides seemed to have some compelling concerns; I am still not sure which side I'm on. The contrast set up between Jenna and Dane was thought-provoking: what defines humanity? Dane is one hundred percent "natural and native species," but is he, really? Is Jenna more human, even though she isn't, technically? Given the gnarly issues, the ending and wrap-up seemed too perfect and too easy.
