So beyond good! I really loved the twins at the heart of this story. I just wish we saw more of Thad and ari together but such a fast pace story. I did not want to put this book down and i love the romance.. I would love to see more of these characters because they were so fun. Some of deaths did make me cry. I adored Ari and how she was like other female in past hero stories and she was unique and i love that.
