The purpose of this paper is to discuss the issue of unreliability in Never Let Me Go by Kazuo Ishiguro deploying the rhetorical approach to narratives - which conceives of narratives as a purposive communicative act - and a range of signifiers and signifieds as defined by Wayne C. Booth, James Phelan and Peter J. Rabinowitz. By contrasting two possible readings of this book, i.e. its common reading as a dystopian novel vs the author’s recommendation of reading it as an allegorical novel, one has the possibility to nuance the issue of reliability.
