Elsa Morante is my favourite Italian writer and I read pretty much everything I could find on her. I was happy to find Lily Tuck's biography, which had a different approach on the life of Elsa. I enjoyed it very much.
Morante is virtually unknown outside Italy and there does not appear to be an English translation of L'Isola di Arturo. This book provides much information about her life and association with Moravia and Pasolini.
