Never Let Me Go
288 pages; Vintage
The Premise: Kathy has loved Tommy since boarding school, but her best friend, Ruth, won him. There's nothing unusual in that setup—but it turns out that all three are clones, created for the sole purpose of having their organs harvested. Kathy becomes a "carer" for other clones going under the knife, which buys her time. Ruth dies on the table. Could Tommy and Kathy's rekindled love win him a deferral?

Why the Ending Is a Stunner: Their former headmistress makes a shattering admission. One that you either suspected (but couldn't believe would actually happen) or that you never saw coming—which, in turn, reveals a little about how you see the world.
