The Story of a New Name by Elena Ferrante
Speaking of which... As this review shows, I was mesmerised by My Brilliant Friend, the first in Elena Ferrante's Neapolitan series. The sequel, The Story of a New Name, has been sitting waiting to be read for some weeks now, but - showing almost heroic resistance to temptation - I've managed to save it for the holiday. The third book, Those Who Leave and Those Who Stay, will also be travelling to the Med.
