As she writes in the final pages: “Life is a gift. But it’s also a responsibility. You have to live it.”

Instead, her mother, a doctor who lost her husband and son in a car accident years earlier, suffers from Munchausen syndrome by proxy. Trapped by her own grief and terror, she manufactured Maddy’s illness, keeping her daughter “safe” by keeping her captive.

Yoon also subtly critiques the medicalization of existence. Maddy has been a patient for so long she has forgotten how to be a person. Her rebellion—choosing to love Olly, choosing to fly on a plane, choosing to risk death for a moment of the ocean—is radical. It suggests that a single day of freedom is worth more than a lifetime of sterile safety. Everything, Everything was a #1 New York Times bestseller, adapted into a major film (2017), and remains a staple in high school classrooms. Why?
