I struggled reading and finishing this book. I loved a few of the characters, Evan and Brenda, their chapters were page turners and exciting. I did had a hard time keeping track of most of the characters, there were a lot of them. I had to flip back and forth to refresh my memory of who they were and where they fit into the storyline. The chapters of the Russian characters, Russian names and acronyms, made it a little more difficult to read and understand. Maybe a list in the back of the book would have helped.
It took awhile, but I did finish the book. I found it interesting but very different from the types of books I normally read. I received this advance reading copy from the publisher for an honest review.
