The Time Traveler's Wife is the debut novel of American author Audrey Niffenegger, published in 2003. 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.
