Landline (novel)

Landline is a 2014 American sci-fi novel by Rainbow Rowell. It tells the story of 37-year-old Georgie McCool who discovers that she is able to call her husband's 22-year-old self through his landline. Rowell stated that aspects from the novel are loosely based on her own life such as the fact that Georgie is incredibly career-driven while her husband is a stay-at-home dad. The character of Georgie McCool was named after the song Georgy Girl and the village of McCool Junction.

While the novel has sci-fi themes akin to time travel, these are used mostly as a plot device to describe the hardships of adult life and the crumbling marriage of main character Georgie McCool.
