Mirror of Shadows — T. Lynne Tolles

Ella McKaye returns home for her grandmother's funeral to find she's inherited a ton of money and a run down mansion she never knew existed, called Grey Manor. Her greedy mother is appalled when the will stipulates specifically that Ella can't give her any of the inheritance. She quickly throws Ella out of her home forcing her to take up immediate residence in the spooky old mansion. Within minutes of entering her new home she has a strange interaction with a creepy old mirror in the main hallway and the ghostly inhabitants of the past get more and more agitated the longer Ella's there. Nearly fatal back to back accidents make Ella start to wonder if she's angered some ghost or if there is something more sinister at work. Will Ella unravel the deadly mystery before she becomes a ghost herself? Or will fate take another one of the Grey ancestors to the grave.
