George Webber has written a successful novel about his family and hometown. When he returns to that town he is shaken by the force of the outrage and hatred that greets him. Family and friends feel naked and exposed by the truths they have seen in his book, and their fury drives him from his home. He begins a search for his own identity that takes him to New York and a hectic social whirl; to Paris with an uninhibited group of expatriates; to Berlin, lying cold and sinister under Hitler's shadow. At last Webber returns to America and rediscovers it with love, sorrow, and hope.
Apparently his copy of Return of the King had all the pages after Aragorn's coronation torn out? I wouldn't go as far as to say something along the lines of "you can't go home again" is the main theme of the book, but it's a pretty strong one (and based on Tolkien's experience in and after WWI). "Nothing ever changes" is about the opposite of what happens.
