Hilary Menos was born in Luton in 1964 and was educated at Wadham College, Oxford, the London College of Printing, and Manchester Metropolitan University. She worked as a Student Union activist, food journalist and restaurant critic with Time Out in London before moving to Devon in 1997 to renovate a Domesday Manor and bring up her three sons.

In 2004, together with her partner Andy Brodie, she set up Beenleigh Manor Organics, a 100 acre mixed organic farm, selling breeding stock and finished beef and lamb. At its peak the farm ran a herd of 40 pedigree Red Ruby Devon cattle and 150 organic Wiltshire Horn sheep. Their son Inigo was born in 2006. In 2011 the decision was made to scale down the farm and by 2013 all farming activity had ceased. She also worked with Exeter-based children's theatre company Quirk Theatre as dramaturge and script overseer between 2012 and 2016, and completed an MA in Creative Writing at Manchester Metropolitan University in 2013. In 2016 the family moved to France to renovate a fifteenth century Templar lodge in the Tarn and develop their web design company, MagicBean.
