"It's catching!!!"
I have never listened to an audio book more than once. I don't intend on starting now.
There is a whole slew of "end of times, apocalypse stories" on Audible, seemingly timed around the rumoured ( and bogus ) Mayan calendar event. A notable number of them seem to involve nano technology. This one certainly is no exception.
That said, it's not a bad example of this subset of fantasy mysteries.
Ferrone does a fine read here, bringing many of the characters to life
Never happened, never will. Doesn't make it a bad story, just impractical for a single session.
This is a good to very good example of nano technology base "end of times" storytelling, and is very enjoyable in that context.
