James Bond: Goldeneye - John Gardner

She is beautiful. She is Russian. And she is very, very dangerous. Once Xenia worked for the KGB. But her new master is Janus, a powerful and ambitious Russian leader who no longer cares about ideology. Janus’s ambitions are money and power: his normal business methods include theft and murder. And he has just acquired Goldeneye, a piece of high-tech space technology with the power to destroy or corrupt the West’s financial markets.
