During a restless summer on the Italian Riviera, a powerful romance blooms between seventeen-year-old Elio and his father's house guest, Oliver. Unrelenting currents of obsession and fear, fascination and desire threaten to overwhelm the lovers who at first feign indifference to the charge between them. What grows from the depths of their souls is a romance of scarcely six weeks' duration, and an experience that marks them for a lifetime. For what the two discover on the Riviera and during a sultry evening in Rome is the one thing they both already fear they may never truly find again: total intimacy.
