The Time Traveler's Wife is the debut novel by American author Audrey Niffenegger, published in 2003. It is a love story about Henry, a man with a genetic disorder that causes him to time travel unpredictably, and about Clare, his wife, an artist who has to cope with his frequent absences. Niffenegger, who was frustrated with love when she began the novel, wrote the story as a metaphor for her failed relationships.
