Simone isn't worried about all of that – she just wants to have fun, scare her friends and distract herself from her own dark secrets.

But in the dead of the night, things begin to go very wrong. When her best friend's life is in danger and Regret appears, Simone must make a choice. How far will she go to save her friend?

Every deal comes with a price ...
