Prior to the publication of What Was Lost she worked in a variety of jobs including deputy manager of a large record shop, post woman, web editor, teacher and mystery shopper. After spending some time in and around Barcelona, she now lives and works in Birmingham, England. She is married to Peter Fletcher, and they have one daughter.
Her first novel, What Was Lost, was published in January 2007. This novel received critical acclaim as an examination of the often lacklustre and empty experience of modern life, contrasted with the energy and optimism of a young girl who went missing in the mid-1980s. What Was Lost was long listed for the 2007 Man Booker Prize for Fiction and the Orange Prize for Fiction, and shortlisted for the Guardian First Book Award. It won the Jelf Group First Novel Award at the Guildford Book Festival and the prestigious First Novel prize at the Costa Book Awards in January 2008. In April 2008 she was named Newcomer of the Year at the Galaxy British Book Awards.
Her second book, The News Where You Are was published on 1 July 2010 and launched the following day at Ikon Gallery in Birmingham. It features the tale of a disenchanted local TV news anchor, who becomes obsessed with the unheralded deaths that he is routinely required to report as part of his day job. One of the stories he follows up has a curious connection to his own life and his seemingly ageless predecessor. O'Flynn was praised for being in this novel the "mistress of compassion" and "the JG Ballard of Birmingham...finding poetry and meaning where others see merely boredom and dereliction".
Her third book, Mr. Lynch's Holiday, was published on 1 August 2013, and tells the story of an estranged father and son, both emigrants from their respective homelands, but for very different reasons. Meeting up in an unfinished (but largely abandoned) housing development in Spain, both are in search of a connection with themselves and each other. The novel garnered numerous favourable reviews for its "brilliant wit and warmth", its "rare love story between a father and a son" and its treatment of "the absurdities of the credit boom", "excelling in exploring the strangeness of being the outsider and the stories people tell themselves to survive".
