Ylva's skis are terrible. Ski trips are lame. Cross country skiing is so hard that she'd rather just hide in the bathroom. But it doesn't work; everyone is going out on a trip. Luckily, the teacher, Monica, keeps her company while the rest of the class goes on ahead. Monica is a good teacher. After a while, Ylva is almost even enjoying skiing! But then there is an accident, and Ylva has to be a skillful and brave skier!
