Which did you find more appealing, the introduction or the conclusion? Neither. I preferred the middle sections when you actually receive an explanation about the ongoing battle and mutants.
Why would you recommend or not recommend this book? I would but only to people who enjoy multiple genres and stories cramped into one story.
Did the book description relate to the story? Mostly, yes. Although, I do think it would be more than helpful if the author included a list of characters and places. Most of us at the book club did this ourselves and without this guide, it would have been confusing.
Disclosure: I received a review copy of this book from the author.
