Sorry it's taken me so long to get back to this but I've been...you know...working on the new story.
Anyway, to those who recently posted their thoughts...many thanks. It's always great to hear people's reactions.
Benny, re: the Progenitors, etc...this was a trail Cambridge was following that ultimately led nowhere for him. But it's not the end of the story as far as Eden goes. Her mysterious past is a large part of ongoing development.
I'll feel more comfortable absolutely confirming the new novel in the next few weeks when it's a done deal. I believe it will be, but when I can, I'll post again with more info.
