I read 'The Handmaid's Tale' not long after it came out. I'm ashamed to say I'm more retentive of movies and some series shows. I remember some of the scenes in the book but I'm one of the 'can't happen here' sort so I took it more as sci-fi than prologue.
I am somewhat embarassed to say that I have also confused Margaret Atwood with Barbara Kingsolver. I read 'The Poisonwood Bible' which I enjoyed, although it does not to me satisfy the OP that it be a NEW ERA book. I suppose it could be interpreted as such, and my friends count listening to a book as equivalent to reading. I've only listened to one book when I was on the road. I suppose it counts. I believe I saw or heard something that the same brain cells are involved either way. I have entered an era in life where I don't believe anything, however, and it's interesting how there is stuff I hear right now, today, which I immediately put the mental kibosh on, and then there's reflection on long held stuff where it comes up as if from some extra cow-stomach to be ruminated on, and in the re-chewing I'm disbeleiving more and more stuff.
