CY's first published work appeared when she was fifteen, within a month of her confirmation: Le Château de Melville; ou, Récréations du Cabinet d'Étude
, written to raise money for the church school at Otterbourne
CY received from her close friend Marianne Dyson
some notes for a story which Dyson had been trying unsuccessfully to get written: this story became The Heir of Redclyffe
CY finished writing the novel which was to make her name, The Heir of Redclyffe
; it was not published for two more years.
In the year of her death CY composed her final work, Reasons Why I Am a Catholic and Not a Roman Catholic
