Wintersmith, by Terry Pratchett, 2006

When she hears the music of a Morris dance ushering in the winter, Tiffany Aching can't keep her feet still. That's how she catches the attention of the Wintersmith, or elemental god of winter, as cold, persistent, and dense a suitor as a 13-year old girl can have. But he's determined to prove himself to her, and the Nac Mac Feegles -- and Roland, the Baron's son -- have an Olympic quest to undergo to save Tiffany and restore the balance of nature, even if Tiffany's not used to being rescued, thank you very much. The third Tiffany Aching story contains more of the same Pratchett absurdity, and plenty of Feegles, but it lacks the luster of books one and two. Recommended.
