p. 120 Not so sure about the story yet, but I do know that I want to visit Florence! p. 312 OK, and Venice. :-)
Finished: I don't agree there is a catastrophe at the end of this story.
What I like best is that this apparently simple action-adventure novel may/should also make people think. If you don't like this solution, what is yours? Because there is this problem. I chose not to reproduce but not enough of us are making that choice. I actually think this is a/the "humane resolution of the problem." --the "thinning of the human herd." I see it as just another recessive gene; it's not as if everyone is fertile now.
