The novel follows twenty-seven-year-old Jet Mason, the daughter of one of the wealthiest families in Woodstock, Vermont. On the night of Halloween, she is attacked from behind and left for dead. She wakes up thirty-six hours later in a hospital with a skull so severely fractured that she is left with the option to either undergo an immediate surgery with a high fatality rate or die of an aneurysm in a week. She declines the surgery, and decides to spend her final week alive finding her attacker.

Shelf Awareness praised it for having the same "propulsive plotting" as Jackson's young adult novels.^[7] In a review for the New York Times, Sarah Lyall called it "surprisingly suspenseful and compelling" despite its "bonkers premise".^[8] In a review for the Washington Post, E.A. Aymar praised the sarcastic voice of the novel's protagonist as the book's biggest draw.^[9] However, he stated that the extent of the protagonist's investment in solving her own murder strains credulity at times, and noted that some readers may find her nihilism and constant quips exasperating.
