I really loved this book it was a edge of your seat action packed spy thriller I loved everything about it. I really loved the characters as well especially X or Huntley is such a great character she does what she wants and is great at it she plays the role she was sent there to be well she is overall a well written character that I will enjoy reading more about sometime. I really liked the story it starts with X at her school she is then called in to do her first mission she finds out many things along the way and falls in love along the way I really liked the romance in the story it was so well written. So overall I loved this book and I will be reading more in the series at some point.
