In this, the final book in the thrilling Spy Girl series, which has spanned a generation, the theme is girl power Bella comes into her own, with her mother Clarisse, her "aunt" Nina, and her unlikely idol Eva to guide her through many major life decisions. Bella tries to get to the bottom of Eva's shady past history with Nina and with her father, Travis, like a sleuth in a suspenseful mystery novel. As she uncovers the sordid details of Eva's former escapades, Bella starts to feel as though almost everyone she loved and everything she believed in is either gone, or has betrayed her. Clarisse, Bella, and Nina must each decide what is more important to them -- to continue to dwell on the heartaches of the past, or to focus instead on the promise of the future. Neither path is without its pitfalls.
