The Flatshare was a unique instance of her writing, as usually her ideas come together from different ideas over the course of time. Her debut novel, however, was inspired by a situation from O'Leary's personal living situation. Her and her now-husband shared a flat but rarely saw each other due to their work shift times. She began to wonder if it would be possible for two strangers to live this way, and how it might develop. O'Leary's characters do not arrive to her fully formed. She says that she learns about them as she writes their story. ==Bibliography==
