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. This book is part of the very popular series Siti's Sisters, featuring Siti and her group of friends, who are so close they call themselves The Sisters.

This is a short, low-level chapter book, with an easy-to-read, fast-moving narrative and is part of Set 2, which is suitable for ages 10+.

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

The Sisters are here!
