Holding Up the Universe Summary: The Full Story
Spoiler warning: This section recounts the entire plot, including the ending.
Holding Up the Universe by Jennifer Niven is set in Amos, Indiana, at Martin Van Buren High School. Libby Strout was ten when her mother died suddenly from a cerebral hemorrhage. Grief and panic attacks led her to overeat until she weighed 653 pounds and became housebound.
Emergency crews had to remove a wall and lift Libby out with a crane, a moment millions watched online. After years of therapy, medical care, and rehabilitation, Libby has lost 302 pounds and is ready to start junior year. She loves dancing and hopes to join the Damsels drill team.
Jack Masselin is a popular senior who appears confident and dates Caroline Lushamp. He secretly lives with profound prosopagnosia, also called face blindness, which keeps him from recognizing faces.
To cope, Jack memorizes voices, hair, gait, and clothing, and he hides behind a cocky personality.
Jack’s home life is strained because his father Nate, a cancer survivor, had an affair with Jack’s chemistry teacher Monica Chapman.
When Jack’s friends Dave Kaminski and Seth Powell introduce a cruel game called Fat Girl Rodeo, Jack writes Libby an anonymous letter about his face blindness and slips it into her backpack. He then grabs Libby in the cafeteria to preempt a worse prank.
Libby feels humiliated and punches Jack in the mouth, breaking his lip. Principal Wasserman sentences both students to community service painting locker rooms and bleachers, plus daily Conversation Circle counseling with Mr. Levine.
Libby also admits to writing negative comments about herself on a bathroom wall as a defense against bullies.

During service and counseling, Libby finds Jack’s letter and becomes the only person who knows his secret.
They begin to help each other: Libby guides Jack through social situations where he confuses classmates, and Jack defends Libby and another bullied student named Jonny Rumsford.
Their connection deepens when Libby encourages Jack to seek a professional diagnosis.
Jack and Libby skip school to visit Indiana University in Bloomington, where neurologist Dr. Amber Klein diagnoses Jack as profoundly face-blind.
On the drive, Jack tells Libby about his father’s affair, and the two hold hands. But after returning, Libby is rejected from the Damsels because of her size, and Jack panics and breaks off the relationship.
Libby responds by walking into school in a purple bikini with “I am wanted” written on her stomach. Supported by Bailey, Jayvee, and Iris, she hands out a printed statement saying everyone is wanted.
The video goes viral. At a party, Jack publicly confesses his face blindness after his parents announce their separation. The crowd laughs, and Moses Hunt attacks him until Libby fights the bullies off.
Libby drives Jack home, and he finally tells his family about his condition. On a Sunday morning in the park, Jack finds Libby and says she is the only person he can truly see and remember because he loves her.
He returns a refrigerator magnet from the day of her rescue, takes her face in his hands, and kisses her, giving both a sense of belonging.
