There were two things everyone knew about Miranda Vaile before she'd even arrived at our school. The first was that she had no parents - they were dead. And the second? They were dead because Miranda had killed them. Olive Corbett is definitely not crazy. Not anymore. These days she takes her meds like a good girl, hangs out with her best friend Ami, and stays the hell away from the toxic girls she used to be friends with. She doesn't need a boyfriend. Especially not a lifesaver-type with nice eyes and a broad back. And she doesn't need the drama of that creepy new girl Miranda trying to make it with her ex-friends. But then, against all odds, Miranda does make it with them. Or she best-friends one of them and makes the others go away. As Miranda emerges from the shadows, Olive begins to realise something sinister going is on. Something almost…parasitic. Either Olive is losing her grip on reality, or those crazy rumours are true. Maybe Miranda is a killer. But who would believe Olive? She does have a habit of letting her imagination run away with her…Shift is a sinister YA psychological thriller that tears through the themes of identity, loss and toxic friendship. It's Single White Female meets Justine Larbalestier's Liar. Shift is the first novel for young adults from Go Girl author Em Bailey.
