"The City of Mirrors" by Justin Cronin is the third novel of a series and continues the story of vampire-like humans in a post-apocalyptic world. As of June 2015, the book has no official release date.
The first book of the series, called "The Passage," tells about the creation of a drug that boosts immunity toward a virus carried by Bolivian bats. The beginning of the story focuses on the virus, while later chapters explore the fictional world 93 years after the infection began. Cronin's original book launched at number three on the New York Times hardcover fiction bestseller list, and two more books were slated to complete the series.
Cronin's second book, "The Twelve," was released in 2012. This book calls back to surviving characters from "The Passage" and then jumps back to describe stories from when the plague first began. Similarly to the first book, Cronin jumps through time to detail the series, introducing new characters along the way.
The series is published by Ballantine Books, which is a division of Random House, Inc., New York. Ridley Scott Productions purchased the rights to the trilogy prior to the release of Cronin's first book, and, as of June 2015, a film adaptation is in the works.
