To Alyx McLean, it's just another summer in London with her Uncle Michael and cousin, Kate. There's the promise of using the 25 languages she knows to translate for Michael at the Intelligence Conference, then attending the Feilds ball, which her uncle hosts every year to wrap up the Conference. Predictable, boring. But the moment she arrives, Alyx knows that this won't be her normal summer vacation. With the arrival of Kate's twin sister, hidden at MI6 since birth, comes the news that changes the course of her summer: Michael's brother, Rafael, is sending his daughter to kidnap Kate. As Alyx races across Europe to save her family, she finds herself with an unlikely team: Stephan, the mysterious and very annoying MI6 agent, and Lyshiria, the Russian girl meant to be their enemy. An American Genius, a British Spy, and a Russian Asset. What could possibly go wrong?
