Shift - Em Bailey

Mean Girls meets Gone Girl - a gripping, dark, psychological thriller for YA readers, perfect for fans of We Were Liars.

There were two things everyone knew about Miranda Vaile. The first was that she had no parents - they were dead. And the second was that they were dead because Miranda had killed them.

Olive hasn't always been a loner - she used to be the school queen-bee. But that was before her breakdown. Now she can only watch as new girl Miranda latches on to her ex-best friend Katie, talking like Katie, dressing like Katie and even going out with Katie's boyfriend.

And then Katie dies. Everyone thinks it was a tragic accident. But Olive isn't so sure. What if Miranda really is a killer . . ?
