On a startlingly bright Autumn night in 2006 Harper Regan walked away from her home and her husband and her daughter and she kept walking. She told nobody that she was going. She put everything she ever built at risk. For two lost days and nights, until it looked as though her entire life might unravel, she didn’t turn back. From Uxbridge to Stockport to Manchester and back again, Simon Stephens’ new play navigates the UK, exploring family, love and delusion; and how to live in a godless universe.
