Mary, will I die?
(Book)

Some legends say if you look into a mirror and say Bloody Mary's name thirteen times, she will show you the future. It might be your one true love... or a skull to mark your death within five years. Others say that conjuring Bloody Mary will bring her into your world. Elena, Steph, Calvin and Grace think it's an innocent game. And only Calvin sees her. They pretend it's all fake... but a demon has been unleashed. Five years later, accidents start happening. And Bloody Mary won't stop until she gets what she wants. -- adapted from jacket
