内容简介：
It is 1968. Martin Luther King, Jr., is assassinated, and then Robert F. Kennedy. If Henry Green graduates a year early, will he be granted the usual four-year deferment from the draft if he goes to graduate school? Should he serve in the Armed Forces of the United States of America or express his opposition to the war in Vietnam by resisting induction? When Henry arrives in France to join an archaeological dig, no one there knows anything about it. With a free summer ahead of him, Henry hitchhikes and takes trains across Europe. While there, he encounters a wide variety of intriguing characters and witnesses historical events that influence his choice. With the rifts of class and religion in his own family on his mind, Henry is distracted by romance as he contemplates a moral course of action.
