I'm around a quarter of the way into Umberto Eco's The Mysterious Flame of Queen Loana.
So far, the novel is fascinating. An antiquarian bookseller in Italy loses his memory and tries to recover it by revisiting publications, people, and experiences. He can recall some historical facts in great detail but the names of his wife and children are initially beyond his grasp. Phrases from various books he's read come jumbling into his speech. And this woman? Was she his mistress?
Different and thought-provoking.
