Hazel lives on a farm with her two mothers and her older brother Rowan. They have a heard of goats that her Mom milks for her business of making soaps and other products, and Mimi is a lawyer in town. Because of a change in the train schedule, Hazel has to go to another middle school, leaving her friend Becca behind for 8th grade. Since a girl at her old school, Kristen, was always very mean, calling Hazel "goat girl" and making fun of her for crying, Hazel wants to make sure she flew under everyone's radar. This is rather lonely, but she eventually finds a table in the cafeteria where she can sit with Yosh, an outspoken boy with a colorful Mohawk who is in a wheelchair, and Carina. Carina went to Hazel's old school, but presented as a boy then. Hazel gets along well with her, and the two slowly become friends. When a school family tree project is assigned, Hazel struggles. She wants to include Lena and Miles, babies that Mimi had who both died before they were born, but doesn't want people to make fun of her. This is an especially sensitive topic because Mimi is pregnant again, and Hazel is beside herself with fear. Even Rowan, who just graduated from high school, took a gap year before going to college because he was concerned about his family coping. When there is a Health and Human Development project to carry around a bag of flour and treat it as if it were an infant, Hazel's concern deepens. It doesn't help that Becca has become a cheerleader, hangs out with Kristen, and doesn't often contact Hazel. When Mimi goes into premature labor, she must reach out to Becca's family for help, and she realizes that she has more support from all of her friends than she realized.
