First, I want to thank everyone for the very positive comments I received on this book. I wish I had more ideas like this one.
I got lots of suggestions about changing things. That's not unusual. Every reader has a unique imagination. In some cases people thought I should change details of the story because they "weren't possible". I get that, too, but this is science fiction, where "anything" is possible.
There was one change, however, that had to be made, because it went too far from reality. That was in the last part of the book, where I had babies being born without some genes. Even in science fiction, that stretches things.
There was a way to fix this, but it would have involved a lot of technical jargon and ethical issues I just didn't want to get into ... for now.
So, if you re-read this book some day, don't be surprised if you see something very different in the last part than you read before.
I just didn't want people writing to ask me if they'd gone crazy. A whole bunch of you lovely readers are old coots, like me, and our memories are a little tired, sometimes.
Thanks for a great time. I really appreciate you all.
Bob
