This study aims at examining the two narrative techniques of an unreliable narrator and embedded narratives in Ishiguro's depiction of friendship and his characters' quest for identity. This can be displayed in Ishiguro's Never Let Me Go (NLMG). It will also be applied to some short stories of Ishiguro's Nocturnes of which the following stories "Crooner", "Come Rain or Come Shine" and "Nocturne" will be chosen. Dzhumaylo has praised Ishiguro for his unique use of "the so-called English boarding school fiction as a ‘platform' for science-fiction dystopia" in NLMG. In contrast to utopia, the dystopian novel often predicts a future that is either pessimistic or full of horror through what is going on in recent times. Lochner emphasizes, "Literary dystopia is to caution against false optimism and the devastating effects of a scientific utopia by projecting present developments imaginatively into the future"(225).
