Dublin, Ireland, 1880. Tired of treating rich hypochondriacs, Dr Will Fitzgerald left his father’s medical practice and his home on Merrion Square to live and practice medicine in the Liberties. His parents were appalled and his fiancée broke off their engagement. But when Will spends a night in a brothel on the eve of his best friend’s wedding, little does he know that the scarred and disgraced young woman he meets there will alter the course of his life.

Isobel Stevens was schooled to be a lady, but a seduction put an end to all her father’s hopes for her. Disowned, she left Co Galway for Dublin and fell into prostitution. On the advice of a handsome young doctor, she leaves the brothel and enters domestic service. But can Isobel escape her past and adapt to life and the chance of love on Merrion Square? Or will she always be seen as a scarlet woman?
