Jane Eyre is a first-person narrative of the title character. The novel goes through five distinct stages: Jane's childhood at Gateshead, where she is emotionally and physically abused by her aunt and cousins; her education at Lowood School, where she acquires friends and role models but also suffers privations; her time as the governess of Thornfield Manor, where she falls in love with her Byronic employer, Edward Rochester; her time with the Rivers family at Marsh's End (or Moor House) and Morton, where her cold clergyman-cousin St John Rivers proposes to her; and her reunion with and marriage to her beloved Rochester. Partly autobiographical, the novel abounds with social criticism. It is a novel considered ahead of its time. In spite of the dark, brooding elements, it has a strong sense of right and wrong, of morality at its core.

Jane Eyre is divided into 38 chapters and most editions are at least 400 pages long (although the preface and introduction on certain copies are liable to take up another 100). The original was published in three volumes, comprising chapters 1 to 15, 16 to 26, and 27 to 38.
