Two years after the events of A Hat Full of Heaven, 13-year-old Tiffany Aching has returned to Lancre to learn witchcraft from the old witch Miss Tenet. In late autumn, Miss Tenet took Tiffany into the woods to watch the dark Morris Dance greeting winter. Despite the ban, Tiffany starts dancing, unable to resist the magic of the dance, and takes an empty place in the row of dancers - a place that was not intended for her, but for Lady Summer herself. The Master of Winter Affairs, in whose honor the dance was performed, mistook Tiffany for the goddess of summer and fell in love with her. And Tiffany, having interfered in something that should not have been interfered with, acquired some of the features of Lady Summer, beginning to become a goddess. The Master of Winter Affairs, or Zimova, begins to seek a meeting with the young witch. He is even ready to become a man for her sake and build an ice palace where they will reign together. How can the elements express their feelings? Tiffany-shaped snowflakes and ice roses may seem quite romantic. But hundreds of icebergs depicting Tiffany and sinking ships, snow storms in the spring when lambs are supposed to be born - this is a completely different matter. The eternal winter that Tiffany Zimova promises will bring death to the whole world. Tiffany must correct the consequences of her foolish act and stop the Master of Winter Affairs. The faithful Nac Mac Feegle and Roland, the baron's son, come to her aid again, and they go to the World of Shadows, where the real Lady Summer sleeps, and wake her up.
