Her Fearful Symmetry is the second novel by author Audrey Niffenegger.
The book was published on 1 October 2009 and is set in London's Highgate Cemetery where, during research for the book, Niffenegger acted as a tour guide.
The novel's title is inspired by The Tyger, a poem by the English poet William Blake, which begins "Tiger, tiger, burning bright / In the forests of the night, / What immortal hand or eye / Could frame thy fearful symmetry?".
Considering the setting of the novel, some critics have also pointed out a potential verbal pun in the novel's title, since in received pronunciation "symmetry" and "cemetery" are almost homophonous.
Elspeth, the aunt of two young identical twins (Julia and Valentina) dies of leukemia, leaving them her apartment which is located beside Highgate cemetery in London.
