As I have read all of these books in this series, I became invested in Regina and her quest to find her sister. The battle between Volpe and Demarco kept the story intriguing and very entertaining. I didn’t know what either lady would do next to try and gain the upper hand. Thus in turn it kept me guessing as to who to trust. Through this journey, Regina has really turned out to be a strong leader but in her book smart, knowledge of the world, and strength. She really is the key to survival of womankind and mankind.
Because I was so invested in the characters and the storyline, it was easy to read this book. I sat down to start reading and just kept reading until I was almost to the halfway point of the book before I put it down. Yet when I picked it up again I was right back into the story until the end. I have enjoyed this series. It is refreshing.
