I remember reading The Passage years ago and really enjoying it. So when I read The Twelve, admittedly only last year, I was not feeling it and was disappointed. It took me hundreds of pages to get back into the story and even then it did not really succeeded. With this information, I was a bit afraid to start with The City of Mirrors, but I wanted to finish the series, and also prevent another huge gap between books.
It was okay. There were parts that I enjoyed, and others that just seemed to be so much filler without actually adding something. Strangely enough though, the part I liked best was Zero's back story. He really fleshed out the characters, and I think this is why I've heard so much great things about his non-fantasy novels. I would certainly pick up one of those books.
However, the survivalist story I liked less. They all feel very safe with the Twelve defeated, but of course, now that there is a new novel, you already know it can't last. It didn't feel very surprising at all, and also to me it was not the last stand that so epic a series (in number of pages at least) should be deserving.
Like I said, I was slightly disappointed with The City of Mirrors, but as Justin Cronin really knows how to portray his characters, I will certainly read more from him in the future!
Thanks to the publisher and Netgalley for providing me with a free copy of this book in exchange for an honest review!
