Personally, I liked the book Eden, it is a bit rough around the edges but it kept me entertained for my commute to work every day. Even got into contact with the writer who is a FAMILY MAN so the 'introduction about the fictional author and about how cool he is in his drifter way' was actually referring to his Ex-partner in writing who got dropped after he was found to be doing those things. Not talking about the writer.
The reason why Okota must've disliked it is because the story line isn't set in beginning-middle-end, it's set anachronically (basically jumping in the story-line of one person backwards and forwards from past to present) This may be two years old and a lot has changed by then, however I'd recommend this book by Far the best I've read, better than WWZ as it Is Not all guns and explosions and there are real life problems rather than just the zombie horde.
But still, you're choice :) Thanks for the recommendation on "As The World Dies"
