I have a bilingual book of tales by Luigi Pirandello, which
I really enjoyed but it is not for beginners.
This ISBN: 1519767269 is related to "The Litlle Prince" in a bilingual edition,
English - Italian. The book was written in French, but is enjoyable and easy.
The on line book sellers offer some books in Italian and English like "Life of Cleopatra",
or "Life of Julius Caesar"; the choice is not really vast.
The tales by Dino Buzzati are finally something very good and not too difficult (please stay away from 'Il deserto dei Tartari'), concentrate over the short stories.
