Seriously, I already enjoyed the first two books of the Newsflesh series, but I never thought I'd want something to be longer in my whole life. This is the intro that all of us wish was written into Feed, but was so much better. It gives all of the details that you wanted and covers a few bases that had you scratching your head after Feed. 
 If Mira/Seannan wrote a longer version of this novella, I would buy it again in a heartbeat.
