In his novel Kazuo Ishiguro has chosen to examine many issues, the most important one being identity. However, throughout Never Let Me Go he also explores the themes of nostalgia and friendship. These three themes are all evident when looking closely at the lives of Kathy H, Ruth and Tommy from the time they are at Hailsham School to the time they become carers and eventually, donors.

The three main themes are:

• identity
• nostalgia
• friendship

Never Let Me Go is a novel which shows what happens when a society is allowed to use scientific experimentation freely and without considering the moral implications. It’s a novel about friendship and about longing for the past, as well as a novel which allows the reader to question the ethics of human cloning.
