Pablo Neruda was an incredibly prolific writer. Consider pairing this with more of his work, including Canto General.
You may want to read work by his teacher and mentor, Gabriela Mistral, or by surrealists like Aimé Césaire and André Breton.
Consider other prominent twentieth-century Chilean authors, including Ariel Dorfman (Death and the Maiden) and Isabel Allende (Eva Luna, The House of the Spirits).
