   [Giovanni's Room] is clearly written out of interior torment, and is an unsparing account of a man fighting against himself. It is certainly not a pleasant book, and David, the narrator, is not "nice" […] but even in its negative ending, it makes a strong statement in favor of self knowledge and accepting one's sexuality.
