Love. Nicola Yoon uses the closing events to show what love costs or achieves, rather than simply stating it.
Overprotection. The ending gives overprotection a final shape, which is why readers often point to it when they explain what the book is really about.
Freedom. Even in the last scenes, freedom keeps shaping the choices the characters make.
Is the Ending Happy or Sad?
Most readers describe the ending of Everything, Everything as Hopeful. That reaction usually depends on what you hoped for the characters and what you expected Nicola Yoon to do with the story, so it is worth asking friends how they felt before you compare notes.
