Agnes Grey, by Anne Brontë

Agnes Grey is a novel written by the English author Anne Brontë and first published in 1847. The novel is about a governess of that name and is said to be based on Anne Brontës own experiences. It was her first novel. Like her sister Charlottes novel Jane Eyre, it addresses what the precarious position of governess entailed and how it affected a young woman.
The Irish novelist George Moore praised Agnes Grey as "the most perfect prose narrative in English letters."
