This is a futuristic novel quite friendly which, if not revolutionize the genre, has the merit of dealing intelligently various topics of interest through a well built strong history, so it is bed with great pleasure.
Even if the scientist is virile and intelligent and his wife as a canon beauty queen, their characters are well drawn and, therefore, credible and engaging. So the issues they face are not case study but painful questions lived, at least for the wife, in their flesh.
She wants a child. It is discovered that the hyper binding legal process making this possible is the product of feminists who wanted to see the requirements parenting skills fully recognized. And it is clear how the best is the enemy of the good.
Other questions so through individual adventures, addressed. Eugenics, as the path leading to pregnancy also involves a partial selection of the individual to be born. The future of the book, the fulguima could doom. The effect of the receipt by an individual, via the Expéron, an experience he has not lived himself. More generally, the novel questions the use of individuals as part of experimental research.
Certainly the themes of reflection does not have a wingspan unusual and the framework is essentially family, bringing this futuristic novel of a comedy of manners and corrected to review the SF mode. But the story works very well and hung me to the point that if I read it in one sitting at least very quickly.
A good read, I recommend even refractory to SF, because the entry in this near future be feasible at relatively low adaptive effort.
