"China Mack will make one final choice. Computer genius China Mack may be the focused head of Vigilance, the government's clandestine spy program, but she can still be knocked off balance. And two back-to-back personal blows have thrown her into a tailspin. Not only is her engagement to tech billionaire Jackson Cooper off but China learns that her mother's death years ago wasn't an accident-it was murder. And China's father, an elusive CIA agent, might have been responsible. To avenge her mother, she needs help. But from Jackson or her loyal friend with benefits, Clark Slattery? When her investigation is linked to a decades-old international plot to hack the New York Stock Exchange, China knows that she'll have to enlist them both. As the three are plunged into a far-reaching conspiracy, China's notions of trust are put to the test. For China, this final case couldn't be more personal-or more dangerous."--Publisher's description.
