Not My Home Anymore

Victoria Greyhold and her Aunt and Uncle are moving into her grandparents home. After her Gran and Pops' death the house has moved into dissaray and they're there to restore it.
Vic sees this as a weight on her shoulders, but as she stays in her childhood home she realises that those whispers and voices aren't only telling her something, they are trying to warn her of something.
Perhaps her grandparents left Victoria one thing before they passed... But what could that something be, and why would her grandparents not tell her?
