Judas, by Amos Oz (Houghton Mifflin Harcourt, 2016), is an exquisite love story and one of his most powerful novels. (“The heart is deceitful above all things, and desperately wicked: who can know it? Thus, spoke the prophet Jeremiah. Thomas Mann writes somewhere that hatred is simply love with a minus sign placed before it. Jealousy is the proof that love is like hatred, because in jealousy, love and hatred are mixed together. In the Song of Songs, in the selfsame verse, we are told that love is strong as death, jealousy cruel as the grave.”)
