Future Survivors, the Apocalypse Group discussion

This is the first of a trilogy of books about a not-too-distant future where young and old are separated by fear and economics. Details and extracts are available on my Good Reads author page and Amazon. There's also a promo video on You Tube using the book title.
What I'd really like is some feedback from members of the group, the book has had positive responses from English readers but I'd be particularly interested in the reaction of American fans of dystopian books. (Good or bad!!)
Thanks.
