Erema; or, my father's sin is a three-volume novel by R. D. Blackmore published in 1877. The novel is narrated by a teenage girl called Erema whose father escaped from England having been charged with a murder he did not commit. Erema has grown up in exile with her father, and the story begins in California in the 1850s. The name "Erema" is taken from a passage in the Greek tragedy Women of Trachis by Sophocles. The heroine of the play, Deianeira, is referred to as erema, a word meaning "abandoned," used by the ancient Greeks for widows and orphans.
