I was not a fan of Tiffany when I read Hat Full of Sky. She seemed...arrogant...to me.
Now, she seems to have grown up a bit.
Her mentor of sorts takes her to a special dance. She's supposed to stand quietly on the sidelines. She doesn't. She joins, and in doing so, manages to interrupt the Summer Lady and the Wintersmith in *their* dance. The Summer Lady goes off in a snit, and the Wintersmith starts courting her. She eventually figures her way out of the mess.
Highlights - extensive visitation with Nanny Ogg. The Mac Nac Feegles.
Lowlights? Well, there weren't any. Tiffany showed growth in this one, and humility.
