Gillian Flynn was born in Kansas City, Missouri to two community-college professors—her mother taught reading; her father, film. Thus she spent an inordinate amount of her youth nosing through books and watching movies. She has happy memories of having A Wrinkle in Time pried from her hands at the dinner table, and also of seeing Alien, Psycho and Bonnie and Clyde at a questionable age (like, seven). It was a good childhood.
Flynn's work has been published in twenty-eight countries. She lives in Chicago with her husband, Brett Nolan, their son, and a giant black cat named Roy. In theory she is working on her next novel. In reality she is possibly playing Ms. Pac-Man in her basement lair.
