Andrew Sean Greer (born 1970) is an American novelist and short story writer.

Biography
Andrew Sean Greer, the child of two scientists, was born in Washington, D.C.. He studied writing with Robert Coover and Edmund White at Brown University, where he was the commencement speaker at his own graduation, where his unrehearsed remarks, critiquing Brown's admissions policies, caused a semi-riot. After years in New York working as a chauffeur, theater tech, television extra and unsuccessful writer, he moved to Missoula, Montana, where he received his Master of Fine Arts from The University of Montana, from where he soon moved to Seattle and two years later to San Francisco where he now lives. He is currently a fellow at the New York Public Library Cullman Center. He is an identical twin.

Work
While in San Francisco, he began to publish in magazines before releasing a collection of his stories, How It Was for Me. His stories have appeared in Esquire, The Paris Review, The New Yorker and other national publications, and have been anthologized most recently in The Book of Other People, and The PEN/ O. Henry Prize Stories 2009.

His first novel, The Path of Minor Planets, was published in 2001.

His second book, The Confessions of Max Tivoli, came out in 2004. Writing in The New Yorker, John Updike called the book “enchanting, in the perfumed, dandified style of disenchantment brought to grandeur by Proust and Nabokov.” Mitch Albom then chose The Confessions of Max Tivoli for the Today Show Book Club and it soon became a bestseller. The story of a man aging backwards, it was inspired by the Bob Dylan song "My Back Pages." Though similar in theme, it is related neither to the Fitzgerald short story nor the film "The Curious Case of Benjamin Button."

Greer's third novel, The Story of a Marriage, received a mixed reception. John Updike revised his earlier assessment of Greer in The New Yorker: "Greer is a prose writer who works on the edge of the overcooked, and there is nothing wrong with that—better that than raw—but can we believe in these highly seasoned sentences as passing through Pearl’s mind?" The Independent noted of the novel, "The author's signposting is not only heavy-handed but typical." The New York Times said of "The Story of a Marriage": "Mr. Greer seamlessly choreographs an intricate narrative that speaks authentically to the longings and desires of his characters. All the while he never strays from the convincing and steady voice of Pearlie.  The Washington Post chose it as a a book of the year, and called it "thoughtful, complex and exquisitely written."
