The Story of the killer of the night

This is a little like UndeadDragonDoll's Murder Mystery book, but probably more gruesome and 'graphic'.

Some people don't worry about dying because they think of themselves so high and protected, but Cher wants to change that. She watched her parents die at the age of 5 and is sick of waiting to get revenge of the rich people who did it. She thinks of herself as Robin Hood. But she doesn't realise they are very different people.
