Lost! (ebook) 

It’s a real pain having to look after younger brothers and sisters, but that’s just what happens when both your parents have full-time jobs. Siti takes her younger brothers and sisters to the shopping centre, but her day goes from bad to worse when she loses track of four-year-old Aifa whilst she is shopping. Can the Sisters help her find Aifa before something terrible happens?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!
