Amnesia (Point Horror)

Alicia wakes up in hospital...to find she's in the middle of a nightmare. Alicia has amnesia. She doesn't even recognize her own face in the mirror. How did she land in hospital? And why won't the doctors tell her anything?

Then Alicia's sister, Marta, arrives to take her home. Surely Marta will help her get her memory back?

But nothing feels right. Could Marta be hiding something from Alicia? Does Alicia's amnesia conceal a terrifying secret? Alicia is afraid to remember - but she could be dead if she doesn't...
