In 1976, Tomás Orilla is a medical student in Buenos Aires, where he has moved in hopes of reuniting with Isabel, a childhood crush. But the reckless passion that has long drawn him is leading Isabel ever deeper into the ranks of the insurgency fighting an increasingly oppressive regime. Tomás has always been willing to follow her anywhere and do anything to prove himself. Yet what exactly is he proving, and at what cost to them both? It will be years before a summons back arrives for Tomás, now living as Thomas Shore in New York. What awaits him is an odyssey into the past, an encounter with the ghosts that lurk there, and a reckoning with the fatal gap between who he has become and who he once aspired to be.
