I give this book most-unjustifiably-boring cover award! Seriously, the cover isn't actively ugly or embarrassing, but it would never have intrigued me into picking up this book. I only read it because it was the selection for this month's Post-Apocalyptic book club meeting - and it turned out to be my favorite of all the books we've read so far.
I'm not sure the six stories in the book (which are linked thematically and through a bit of structural gimmickry) really needed to be presented as one work, but since all of them were interesting, and a couple of them were excellent, I didn't mind.
Update: I've belatedly decided to up my review to 5 stars, from my initial 4 - because this is a book I find myself repeatedly thinking about, and recommending to people. It holds up to consideration.
