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.

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.
