From Wikipedia:

"Annabel Lee" consists of six stanzas, three with six lines, one with seven, and two with eight, with the rhyme pattern differing slightly in each one.

Like another Poe poem, "The Raven", it tells of a man mourning a dead lover. The poem begins as if from a storyteller's point of view, wherein the author begins to explain the couple's love, which originates from their childhood. He believes that his love Annabel Lee dies because "the angels" envied the couple's great love. However, unlike "The Raven," in which the narrator believes he will "nevermore" be reunited with his love, "Annabel Lee" says the two will be together again, as not even demons "can ever dissever" their souls.
