As part of the school's community week, Donna decides to spend a week helping at the stables. That's fine - she loves horses - but the three other girls she has to work with are stuck-up and always nasty to her. When the other three start messing about, there's nearly a serious accident.

The issues presented are, as always in this series, relevant and appealing to girls of this age. The Sisters are here!
