The Go-Between - L. P. Hartley

When one long, hot summer, young Leo is staying with a school-friend at Brandham Hall, he beings to act as a messenger between Ted, the farmer, and Marian, the beautiful young woman up at the hall. He becomes drawn deeper and deeper into their dangerous game of deceit and desire, until his role brings him to a shocking and premature revelation. The haunting story of a young boy's awakening into the secrets of the adult world, The Go-Between is also an unforgettable evocation of the boundaries of Edwardian society.
