Benjamin and Helen Rask are an extremely wealthy, Depression-era couple engulfed in rumors: some about his financial practices, and others centered on her reclusiveness. Hernan Diaz’s novel Trust, which is constructed as four parts—including a novel within a novel, a memoir, and a journal—reveals the truth about how they acquired their fortune. Trust us: you won’t want to believe or take for granted anything presented as fact in this story. Diaz delivers a satisfying literary puzzle that’s compelling and creative. —Angela Haupt
