I believe that the idea of loss serves as a source of haunting in this novel. From the beginning, Kathy, who is beginning to reach the end of her life, is grasping to her memories of the friends she’s had and the life she has lived as it all continues to slip between her fingers. This is supported by the way the narrative is told in a nonlinear manner with a restrospective focus.
I believe the concept of deferrals was Kathy’s attempt at riding herself of this haunting, but it too supports the idea of loss and ultimately it’s inevitability. A deferral only provides a momentary extension of life, it is not an excuse or an exclusion from completion – or death. Which feeds into itself, because the foundation of the donation program is that people on the outside would be able to extend their lives with the students’ internal organs.
This novel really made me contemplate how haunting doesn’t have to just be from something that has passed, but from the impending passage of one’s time, one’s life or one’s relationships. Honestly, I believe this form of haunting is even more relentless than by that of something that is over. This because there is a sense of power in existing beyond whatever is haunting you from the past, but the idea that the source of your haunting exists after you pushed the fact that you will never be rid of its ominous presence and the fear it may cause. I think the best way to sum up this novel is the fear and endless truth that the phrase Momento Mori provides: Reminder that you will die.
