Loin d'être un récit moralisateur, Emily Brontë achève néanmoins le roman dans une atmosphère sereine, suggérant le triomphe de la paix et du Bien sur la vengeance et le Mal.

An Autobiography), erstmals erschienen im Jahr 1847 unter dem Pseudonym Currer Bell, ist der erste veröffentlichte Roman der britischen Autorin Charlotte Brontë und ein Klassiker der viktorianischen Romanliteratur des 19. Jahrhunderts. Der Roman erzählt in Form einer Ich-Erzählung die Lebensgeschichte von Jane Eyre (ausgesprochen /ˌdʒeɪn ˈɛə/), die nach einer schweren Kindheit eine Stelle als Gouvernante annimmt und sich in ihren Arbeitgeber verliebt, jedoch immer wieder um ihre Freiheit und Selbstbestimmung kämpfen muss. Als klein, dünn, blass, stets schlicht dunkel gekleidet und mit strengem Mittelscheitel beschrieben, gilt die Heldin des Romans Jane Eyre nicht zuletzt aufgrund der Kino- und Fernsehversionen der melodramatischen Romanvorlage als die bekannteste englische Gouvernante der Literaturgeschichte
