Maybe you’ve read Boris Pasternak’s Doctor Zhivago or you’ve seen the film of the same name from 1965, directed by David Lean and starring Omar Sharif and Julie Christie. Or perhaps you’re familiar with “Lara’s Theme,” the song from the movie. At any rate, we bet you’re at least a little bit familiar with the love affair between the fictional characters of Yuri and Lara. A new book by Anna Pasternak, the granddaughter of Boris’s sister Josephine, reveals details of the love affair between Boris Pasternak and Olga Ivinskaya, which served as the inspiration for the novel. The book is entitled Lara: the Untold Love Story and the Inspiration for Doctor Zhivago. It was released in January 2017.
