Trust by Hernán Díaz

Even through the roar and effervescence of the 1920s, everyone in New York has heard of Benjamin and Helen Rask. He is a legendary Wall Street tycoon; she is the daughter of eccentric aristocrats. Together, they have risen to the very top of a world of seemingly boundless wealth—all as a decade of excess and speculation draws to an end. But at what cost have they acquired their immense fortune? This is the mystery at the center of *Bonds*, a successful 1937 novel that all of New York seems to have read. Yet there are other versions of this tale of privilege and deceit.
