I never had a single complaint with the book. I find assassins more interesting than most people and read about them and play them in video games often. The characters were solid so far, the setting and how it became was intriguing, and there was enough mystery behind Yelena’s past to keep someone interested from beginning to end. As someone who doesn’t like romance as the main focus I thought it was well done, by the time the love interest was presented I loved them both and was rooting for things to work. Everything about this book worked for me. Snyder has set up a wonderful series that I can’t wait to continue.
