The book is wonderfully written, and actually fairly insightful from a disaster preparedness and policy standpoint. It's been a while since a read it so forgive me if the details aren't exactly correct. Its written from the viewpoint of a journalist traveling the world post zombie apocalypse. He is collecting stories from survivors of various major events that happened during the zombie outbreak. Each chapter details a different event conveyed by a different witness, so it's not a cohesive single plot story. More like working notes of someone preparing to write a history of a major global disaster. It highlights some of the mistakes made and lessons learned as events unfolded.
