Home-care nurse Emily Klein can’t get out of her new assignment – weekly prenatal visits to Pippa Glenning, a young Isis cult member under house arrest for the death of her daughter during a Solstice ceremony. But she takes her work seriously and plays by the rules, so Emily is determined to take good care of her high-profile and unconventional patient. With two other cult members in prison, Pippa Glenning struggles to keep the household intact. If she follows the rules of her house arrest, she may be allowed to keep her baby; but as the pregnant woman in the family it’s her duty to dance for Isis at the upcoming winter Solstice ceremony. To escape the house arrest without being caught, Pippa needs Emily’s help. Despite their differences, Emily and Pippa’s friendship grows. Returning to Maine for her grandfather’s funeral, Emily begins to grapple with her parents’ activism a generation earlier and her father’s death in prison. Back home, as the Solstice and the trial approach, anti-cult and racist sentiment in the city escalates. Emily and Pippa must each make decisions about their conflicting responsibilities to their families and to each other – decisions that put their lives, and Pippa’s unborn baby – in jeopardy.
