One beautiful September day, three sixty-six-year-old men convene on Martha's Vineyard, friends ever since meeting in college in the 1960s. They couldn't have been more different then, or even today - Lincoln's a commercial real estate broker, Teddy a tiny-press publisher and Mickey an ageing musician. But each man holds his own secrets, in addition to the monumental mystery that none of them has ever stopped puzzling over since 1971: the disappearance of their friend Jacy. Now, decades later, the distant past interrupts the present as the truth about what happened to Jacy finally emerges, forcing the men to reconsider everything they thought they knew about each other.
