"Edge" is thought to be the final poem Sylvia Plath ever wrote. Dated February 5, 1963, six days before her death, "Edge" has been read by many critics (though not all) as a reflection of her despair and suicidal thoughts. It depicts an eerie scene in which a mother and her two children lie dead beneath a staring, indifferent moon. Though the speaker claims the deaths are "nothing to be sad about"—from the moon's perspective, at least—the poem's hints of exhaustion, depression, and family conflict lend it a disturbing, tragic atmosphere. "Edge" was first collected in Plath's posthumous volume Ariel (1965).
