The H-Bomb Girl by Stephen Baxter

The Cuban Missile Crisis was, of course, a major event in the United States and Soviet Union in 1962, but it also affected other countries in the world. The book is a young adult time-travel/alternate history novel that looks at the crisis from the point of view of a fourteen year old girl in Liverpool. Laura Mann has newly arrived in Liverpool and must deal with the typical relocation issues, as well as an absentee father and parents going through a divorce when her world is really turned upside down.
