Keegan has cited Anton Chekhov as an influence on her work. Chekhov was a Russian playwright and writer who is often considered one of the greatest short story writers of all time. Many of his short stories can be found in the book
Selected Stories of Anton Chekhov, published in 2000. Keegan has also named Flannery O’Connor as an influence. Some of O’Connor’s most well-known works include the novel
Wise Blood and the short story collection
A Good Man is Hard to Find and Other Stories. Another influence of Keegan’s is the writer John McGahern, whose most prominent novel,
Amongst Women, is about an aging former IRA soldier who fought during the Irish Civil War in the 1920s. Keegan is primarily a short story writer, and her work has been compared to that of William Trevor, an Irish writer who was also considered a master of the short story. Trevor wrote several novels as well, which, like
Foster, depict life in rural Ireland. Some of Trevor’s most well-known novels include
The Story of Lucy Gault and
Love and Summer.
Foster takes place during the Troubles in Ireland. One well-known nonfiction account of the Troubles is
Say Nothing by Patrick Radden Keefe.
