Plot
The summer of 1960 is a season that the novel's narrator and protagonist, 11-almost-12-year-old Hattie Owen, expects to be as comfortably uneventful as all the others had been in her small, tranquil town of Millerton, Pennsylvania. She's looking forward to helping her mother Dorothy run their boarding house with its eccentric adult boarders, painting alongside her father Jonathan, and reading.

Then 21-year-old Uncle Adam, whom Hattie never knew existed, comes to stay with Hattie's grandparents (Nana and Papa), because his "school," an institution for the mentally disabled, has closed down permanently. Intelligent, childlike, and strange owing to his disability, Adam visits Hattie often. Adam quickly becomes smitten with Angel Valentine, the beautiful and most recent lodger to check into the Owen boardinghouse.

Hattie then meets Leila, the daughter of the carnival owners who come to town. However, after Adam suffers a mental breakdown on the Ferris wheel, she moves away with the carnival.

Throughout the summer, other people come to stay at Hattie's boarding house, such as a woman, Mrs. Strowsky, with a son Sam and daughter Catherine. She recently suffered the death of her husband and moved away, but needed a place to stay while job hunting.

As various other events mark Hattie's "uneventful" summer, she comes to better understand Adam. However, when Adam unintentionally walks in on Angel with her boyfriend Henry, he is upset and runs off. His body is later found, revealing he had died by suicide. Hattie is devastated. Before Adam's funeral, Hattie asks her mother if she loved her brother. She snapped at Hattie, and said it was hard to love him. Hattie speaks at the funeral about Adam, and afterward, she discovers his treasure box, which he kept all the letters and objects Hattie's mom sent him. She realized her mother did actually love Adam.

Two months later, Angel moves out with Henry. Hattie's family cleans out Adam's room. Mrs. Strowsky found a job, and they move out. The book ends with Hattie turning off a film of Adam, and she realizes he revealed a corner of her Universe.
