Rachel's jealous of her older brother Wil, who's been invited to lots of parties. Wil agrees to take Rachel to one of the parties - but of course everybody's older than Rachel. But that doesn't matter - Wayne, who she fancies, will be there. Rachel feels like a bit of an outsider until one of the boys starts chatting her up and fetching her drinks. Before long the party's over, leaving Rachel feeling horribly ill and both Wil and Rachel facing the consequences. 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!
