IMHO it's a pretty fun book, great for a long train ride.
However it's a little problematic in places, with some weirdness with eugenics and the role of women's reproduction. Trying to be vague to prevent spoilers.
Yeah, that part seemed a little forced, as if he was working backwards from the title, to accidentally arrive at the good stuff that comes before that in the book. Which makes it a good read nonetheless.
