In this exploration of the varieties of love, the author of ‘Call Me by Your Name’ lets us back into his characters’ lives years after their first meeting. In ‘Find Me’, Aciman shows us Elio’s father, Samuel, on a trip from Florence to Rome to visit Elio, now a gifted classical pianist. A chance encounter on the train upends Sami’s visit and changes his life forever. Elio soon moves to Paris, where he, too, has a consequential affair, while Oliver, a New England college professor with a family, suddenly finds himself contemplating a return trip across the Atlantic. Aciman is a master of sensibility, of the intimate details and the nuances of emotion that are the substance of passion.
