The idea of the novel is fairly simple: Children (clones) are raised for the strict purpose of donating their organs to "normal" people, but the emotion in the novel sticks with you long after you have finished reading. (I still have nightmares about it.)
Amazon Book Description:
From the Booker Prize-winning author of The Remains of the Day comes a devastating new novel of innocence, knowledge, and loss. As children Kathy, Ruth, and Tommy were students at Hailsham, an exclusive boarding school secluded in the English countryside. It was a place of mercurial cliques and mysterious rules where teachers were constantly reminding their charges of how special they were.
Now, years later, Kathy is a young woman. Ruth and Tommy have reentered her life. And for the first time she is beginning to look back at their shared past and understand just what it is that makes them special–and how that gift will shape the rest of their time together. Suspenseful, moving, beautifully atmospheric, Never Let Me Go is another classic by the author of The Remains of the Day.
