I just finished reading World War Z by Max Brooks, which is #87 on the list of 100 books the algorithm in The Bestseller Code (Jodie Archer and Matthew Jockers) thinks you should read. I enjoyed it – my review is on Goodreads if you’re interested – and one of my compatriots in this 100-book journey suggested looking back at The Bestseller Code to try to understand why this was chosen.

Theme and topics

The algorithm says that bestsellers limit their focus. They give 30% of their paragraphs to just one or two topics. This focus brings both depth and a story that can be easily followed by the reader. WWZ clearly hits this mark: everything in the book is about the zombies – how the plague got started, how it spread, how it affected the world, and how humanity fought back.

As for secondary topics, an important one is work – TBC mentions Stephen King’s assertion that readers love to read about work, and in WWZ, which is structured in the form of interview notes with people who lived through the crisis, almost all the interviews are with people who were doing their jobs. We read about pilots, astronauts, soldiers, doctors, and sleazy profiteers.

Maybe the absence of human closeness as an important secondary topic – it comes up some, but not a lot – helps explain why this is ranked #87 on the list and not higher. On the other hand, the book is sound on dogs, another important feature to the reading public. And it includes lots of modern technology, with descriptions and even footnotes about military vehicles and weapons.

Pace and plotting

Bestsellers break up the tension with scenes of ordinary life, giving readers a chance to catch their breath. I think the lead-ins to the interviews serve this function: they provide a little background about the person being interviewed and the life they’re living now, after the worst is over.

The algorithm identified 7 patterns in ups and downs of bestseller plots. I think WWZ matches one of them pretty well. It’s the same one that fits Stephen King’s The Stand, another story where humanity is decimated by a terrible plague and the world is changed forever. The key seems to be that the curves need to be steep enough to grab the reader. WWZ gives us a plummeting downhill slope from warnings and blame to the great panic; gives us something to cheer about when people figure out how to fight back; and then drags us down again with what’s happened to the world and the seemingly endless task of eradicating the remaining zombies.

Style and voice

Readers like voices that speak with authority, like Jane Austen’s famous first line in Pride and Prejudice: “It is a truth universally acknowledged, that a single man in possession of a good fortune must be in want of a wife.” And many modern readers like language that sounds like the way people talk, which TBC calls the journalistic (as opposed to literary) style and, by the way, identifies with women writers. The structure of WWZ does this brilliantly. The interviewer barely appears, so each piece is the transcribed speech of a person who lived through events and has had time to reflect on them and decide what they think about it. While I was reading the book, my only quibble was that not all the voices were differentiated from each other.

Characters with agency

Finally, readers like characters who do things. WWZ‘s 100-ish interviews are all with people who did something. The algorithm identifies this through analyzing word choice. Flipping back through the pages of WWZ, I see flying, guard, make a stand, risk, drop, climb, slam, shoot, grab, drilled, jazzed, all showing characters doing stuff. The book also has some good, strong female characters. And let’s not forget the dogs, who sniff, hunt, launch themselves, and lure.
