While I liked the characters of Olivia and Jessie, both Lynch and Kendra annoyed me. The plot of this story also led to what would obviously be the next book. They were all following an evil company to follow to Afghanistan, where they hoped to get more information to close them down. Then there was the serial killer twist, which wasn't really a twist at all.
I expected a little more out of this book. While I didn't hate it, I didn't love it, and I felt that the more interesting characters didn't get enough time in the story. Even the ending disappointed me a little as Olivia had something horrible, yet not horrible happen to her. I was a little confused by what happened. I'm not sure I will read another book in this series. Usually, if I pick up a book in a series that is one set in the middle somewhere, I feel the need to go back to the beginning of the series, to learn more about the development of the character. I didn't feel the need with this one. And I really do have a with the fact that six books in the main protagonist, Kendra, has had twenty-seven attempts on her life.
If you have enjoyed the series, and have read other books in it, you may like this one more than I did.
