Based on his earlier short story, "Phineas," it was Knowles' first published novel and became his best - known work . Set against the backdrop of World War II, A Separate Peace explores morality, patriotism and loss of innocence through its narrator, Gene . </P> <P> Gene Forrester, the protagonist, returns to his old prep school, Devon (a thinly veiled portrayal of Knowles' alma mater, Phillips Exeter Academy), fifteen years after he graduated to visit two places he regards as "fearful sites": a flight of marble stairs and a tree by the river that he caused his friend, Phineas, to fall out of . First, he examines the stairs and notices that they are made of very hard marble . He then goes to the tree, which brings back memories of Gene's time as a student at Devon . From this point, the novel follows Gene's description of the time span from the summer of 1942 to the summer of 1943 . In 1942, he was 16 and living at Devon with his best friend and roommate, Phineas (nicknamed Finny). At the time, World War II is taking place and has a prominent effect on the story . </P> <P> Gene and Finny, despite being opposites in personality, are close friends at Devon: Gene's quiet, introverted, intellectual personality is a character foil for Finny's extraverted, carefree, athletic demeanor . During his time at Devon, Gene goes through a period of intense kinship with Finny . One of Finny's ideas during Gene's "gypsy summer" of 1942 is to create a "Super Suicide Society of the Summer Session", with Gene and himself as charter members . Finny creates a rite of initiation by having members jump into the Devon River from a large, high tree . </P>
