Very interesting concept. Most "living dead" stories take place around the event itself or in the immediate aftermath of the event (within 1 lifetime). In constrast, CR speculated about how society would develop over time. This story takes place generations after the initial outbreak and it makes for an interesting conflict for the characters. They don't know how the sickness started, all they have is rumors and knowledge grudgingly handed out from the Sisterhood. The only world they know is their village and, again, rumors of what life was like before. Mary grew up in this world but refuses to accept that things have to remain the same. She has a few character flaws. Her immaturity and selfishness is annoying at times, but overall I enjoyed this book.
