This is the third installment of the Gwendy's Button Box trilogy. Previous installments include Gwendy's Button Box and Gwendy's Magic Feather. Set primarily in the future year of 2026 on the MF-1 Space Station, it revolves around the eponymous Gwendy Peterson, a sixty-four-year-old United States Senator from Maine. It has been twenty years since Richard Farris relieved her of the button box, but now it is back and she must face overwhelming obstacles before she can destroy it once and for all.
