All three books are here for you and the box set has enough material to keep you engaged for the whole week. The seventeen years old Sienna gets into real trouble from the start of the story. The first part starts when Sienna is scene locked in her house by her own mother. Her mother didn’t allow her to go out of the house for twelve years because of some unknown reasons.
Then one day the girl was amazed to see that the house was empty and her mother was nowhere to be found. Instead of her mother, there were two strangers in her house who wanted to take her with them. Sienna ran from the spot and didn’t look back afterward. Later she realized that a strange organization was following her because she had some super powers which she was unaware of previously.
For six months the girl kept on running and during this time she got her training too. Finally in the last part of the series we observe that Sienna is ready for her first mission and she can take care of things on her own. Robert J. Crane started the series when the girl was unaware of her powers.
After every episode, Sienna became more and more powerful and finally, she made her enemies run. Defender and Omega are single books and getting the box set is always a better thing. Annie Sullivan has narrated all three parts of the series so her voice is the only voice that you will hear. Moreover, there is no change in the theme or mission of the characters so a single focused heroine is witnessed in the story.
