From the American invasion of Iraq in 2003 to the terrorist attacks in Paris in 2015, Paris Metro is a story of East meets West. Kit, a reporter, has spent several years after 9/11 living in the Middle East, working as a correspondent for an American newspaper. Along the way she falls in love and marries a charismatic Iraqi diplomat named Ahmed, before their separation leaves Kit raising their teenage son alone in Paris. But after the Charlie Hebdo attack occurs and, a few months later, terrorists storm the Bataclan, Kit's core beliefs are shattered. The violence she had spent years covering abroad is now on her doorstep. As Kit struggles with her grief and confusion, she begins to mistrust those closest to her: her friends, her husband, even her own son.
