The Time Traveler’s Wife, published in 2003, is the debut novel of American author Audrey Niffenegger. It is a love story about a man with a genetic disorder that causes him to time travel unpredictably, and about his wife, an artist, who has to cope with his frequent absences and dangerous experiences. Niffenegger, frustrated in love when she began the work, wrote the story as a metaphor for her failed relationships.
She has said the story is a metaphor for her own failed love affairs and that “I had kind of got the idea that there’s not going to be some fabulous perfect soulmate out there for me, so I’ll just make him up.”
Instead, as critic Marc Mohan describes, the novel “uses time travel as a metaphor to explain how two people can feel as if they’ve known each other their entire lives”.
