When Charlotte McCagin was ten, she didn't want to be a CIA agent. But when the Agency realizes she is a savant with an incredible ability to absorb skill and knowledge and apply it under pressure, Charlotte is whisked away from her family, school and friends to learn the tricks of the trade and fill the shoes her father, a U.S. Senator and former spy, left behind. While at school, Charlotte uncovers a file that reveals a hidden secret in her dad's past - a mission he and his team never completed and that sidelined his CIA career. Charlotte has a funny feeling that she was chosen for more than just her talent. The file contains few clues: an old rhyme that is somehow connected to The Canterbury Tales; a list of names of her dad's old team - which happens to include the names of the parents of her best friend and CIA confidant, and even worse, the father of her new boyfriend; and a dead body that leads her to Moscow. On her sixteenth birthday, Charlotte is given her first assignment. Soon she is following a money trail to uncover the identity of a source who funds aggressive revolutionists and guerrilla warfare across the world. At the mercy of a mysterious source who feeds her information through cryptic poetry, Charlotte falls into a rabbit hole of old-school espionage, forcing her to choose between the love of a boy and finding the truth to vindicate her dad.
