It's a few days before Donna's birthday, but her parents just can't afford to throw her a big party. To make matters worse, people are acting strangely around her. Her two older sisters don't want to come to her childish party, and the Sisters don't seem to want to talk about her birthday at all! Has Donna done something wrong? 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 1, 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!
