I've been rereading Terry Pratchett's series with Tiffany Aching (witch-in-training) and the Nac Mac Feegle (or "Wee Free Men" or "six-inch tall blue highlanders"), so this past weekend I finished Wintersmith for the second time.
Tiffany Aching gets more than she bargained for when she disobeys the rules and joins in a dance of the seasons. The Wintersmith, spirit of winter, confuses her for Spring and falls in love with her. The only problem is that the Wintersmith isn't a man, and he's trying to woo her with Tiffany-shaped snowflakes and Tiffany-shaped icebergs, and he's bringing on the worst winter ever to impress Tiffany with his strength.
That's actually not the only problem. But that's the biggest.
