This is what we found on Wikipedia regarding the The Time Traveller's Wife:

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. The tale's central relationship came to Niffenegger suddenly and subsequently supplied the novel's title. The novel has been classified as both science fiction and romance.

The book was published by MacAdam/Cage, a small publishing firm located in San Francisco, California. The book became a bestseller after an endorsement from author and family friend Scott Turow on NBC's Today. As of March 2009, the novel had sold nearly 2.5 million copies in the United States and the United Kingdom. Many reviewers were impressed with Niffenegger's unique perspective on time travel. Some praised her characterization of the couple, applauding their emotional depth; while others criticized her writing style as melodramatic and the plot as emotionally trite. The novel won the Exclusive Books Boeke Prize and a British Book Award.

Warner Bros. and New Line Cinema acquired the film and television rights to the book. A film adaptation was released in 2009 starring Rachel McAdams and Eric Bana, and a television series premiered on HBO and HBO Max on May 15, 2022.
