One of the Sisters' classmates, Michelle, has started hanging out with a new group of friends. They're older and the girls know that they're into drugs. When they find Michelle in the toilets being sick, the Sisters don't know what to do. Michelle admits that she's tried some stuff and is really frightened. The Sisters do their best to help, but who can they tell? 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 3, which is suitable for ages 12+, since some of the stories touch on more grown-up topics such as friends who take drugs and going to parties. The issues presented are, as always in this series, relevant and appealing to girls of this age. The Sisters are here!
