Harriet must choose between her friend Lalla and her new-found love of ice-skating...

If you pass your inter-silver, I'll tell Aunt Claudia that I don't want to work with you any more.

Harriet is told that she must take up ice-skating in order to improve her health. She isn't much good at it, until she meets Lalla Moore, a young skating star. Now Harriet is getting better and better on the ice, and Lalla doesn't like it. Does Harriet want to save their friendship more than she wants to skate?
