Choosing one book for a Ferrante reader

Hi everyone,
I’m choosing one book as a gift for someone who loved Elena Ferrante (especially the Neapolitan novels). I’m looking for a similar emotional and literary core.

These are the final contenders after researching online

• Quaderno proibito (Forbidden Notebook) – Alba de Céspedes
• Lessico famigliare (Family Lexicon) – Natalia Ginzburg
• Az ajtó (The Door) – Magda Szabó
• Nada (Nada) – Carmen Laforet
• The Bell Jar – Sylvia Plath

If you had to choose one of these for a Ferrante reader, which would you pick? Any other suggestions?
