Eleven-year-old Hattie Owen lives with her mother and father in Millerton, a town in the northeastern United States, during the 1960s. Her parents run a boarding house where several boarders have been living for years, and Hattie has become friends with all of them—the elderly Miss Hagerty who loves to sew and knit; Mr. Penny, a retired watchmaker who loves clocks; and the newer resident, Angel Valentine, a beautiful young woman who works at the bank. Hattie is very comfortable in her life and enjoys the familiarity of her family and the friends who live in the house with her.

The special home that had been taking care of Adam is closing, so Adam is coming home to live with Nana and Papa again until they can find another place for him.

Adam arrives and is a very interesting, unique character. He swings between feeling ecstatically happy, intensely angry, and incredibly sad—all very quickly and without warning. Also, he is overwhelmed by a lot of noise and sensory stimulation, which causes him to have panic attacks.
