Before becoming a published writer, she joined the BBC at 21 under the name Alison Feeney-Hart, where she worked as a producer and journalist for approximately 15 years. She became a producer for the One O'clock News, a reporter and news editor, and a producer for arts and entertainment programmes.
Feeney started writing her first novel, Sometimes I Lie, when she was 30, writing in her spare time and on the train to work. She took the Faber Academy writing course, finishing the book and course around the same time.
Adaptations
In 2019, Fox bought the television rights to Sometimes I Lie. In November 2019 a television series project was announced, with Sarah Michelle Gellar playing the lead role. Robin Swicord was engaged to adapt the book, and Ellen DeGeneres and Jeff Kleeman, as well as Gellar and Swicord, were to be executive producers. This option later lapsed, and the rights were picked up by Tommy Harper Productions and Matt Charman's Binocular Productions in 2024. Charman and Caryl Lewis are set to write the adaptation.
