Elena Ferrante ends Those Who Leave and Those Who Stay on a cliff-hanger. She is a literary novelist, but her commercial instincts are strong. What will happen to Elena Greco after she walks out on the life she has made for herself? Can't wait for Book Four to arrive. The one lovely twist to Book Three of her series is that this one focuses more on Elena than her brilliant friend Lila. Frankly, I'm frightened by Lila. So glad she exists only within the pages of a novel. But Elena Greco? She's me, she's all of us. Elena Ferrante shows us ourselves in her illuminating series. Absolutely cannot put down her books.
