You might have heard of Karen McManus thanks to her previous books: One of Us Is Lying; Two Can Keep a Secret; and One of Us is Next. Sadly, her new book does not contain the word three. What it does contain, however, is a smart and impressively thought out plot that will leave your jaw on the floor. As Christmas approaches, and with it the traditional family disputes (though this year at least, we might avoid those), reading about a family where death and misery are almost every day occurrences may sound quite appealing. Yes, Granny might judge your Christmas pudding… but at least she’s not about to murder you. A brilliant example of what Young Adult thrillers should be, packed with loads of suspense and amazing characters.
