Reuven Malter lives in Brooklyn, he' s in love, and he' s studying to be a rabbi. He also keeps challenging the strict interpretations of his teachers, and if he keeps it up, his dream of becoming a rabbi may die. One day, worried about a disturbed, unhappy boy named Michael, Reuven takes him sailing and cloud-watching. Reuven also introduces him to an old friend, Danny Saunders– now a psychologist with a growing reputation. Reconnected by their shared concern for Michael, Reuven and Danny each learns what it is to take on life– whether sacred truths or a troubled child– according to his own lights, not just established authority. In a passionate, energetic narrative, The Promise brilliantly dramatizes what it is to master and use knowledge to make one' s own way in the world
