3 stars because it was rather - let's say - uneventful. The idea with the virus and the corn was funny (yeah funny with that apocalypse thingy). Basically all the main character and her friend did was travelling around Chicago and shooting Z's while making a plan about going north and south. Because there might be some peace or normal people out there. That's about it. The end makes me want to read the sequal and started me to dislike the main character and her believes. Maybe she gets better.
