The Sisters are having a sleepover at Lu''s. After watching horror DVDs in Lu''s bedroom, it''s time to go out to the summer house in the garden where they''re all meant to be sleeping. But there are all kinds of spooky noises outside and then the burglar alarm goes off. Lu''s parents aren''t sympathetic and don''t believe the girls when they say it wasn''t anything to do with them. But what was it? 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!
