Alexandria Song, or Alex if you know her, which most don't. She's your typical teenage girl. She goes out with friends, does her homework, reads books, listens to her parents, and knows how to kill a man in more ways than one. Okay, maybe not so typical. Since she was nine years old, her father had been teaching her 'self-defense' to the extreme. She learned in a few short years how to handle knives, guns, and poisons. One night, she's lying in bed, sleeping, when she heard a sound from downstairs. She never imagined that sound to tear her away from her stable life and away from her family. This particular noise is Seven, an assassin sent to kill Alex's parents. Failing in his mission, he takes Alex with him before he leaves. In a whirlwind of events, Alex learns the truth behind her life. She learns the truth about her deceiving parents and more about this assassin named Seven, who is adamant about getting her to this 'secret place.'
