A vision in velvet

"As soon as Lily opens the trunk, she feels strange vibrations emanating from a mysterious velvet cloak. When she tries it on, Lily sees awful visions from the past. And when the antiques dealer who sold her the cape is killed, Lily suspects a supernatural force might be behind his death. Then Lily's familiar, Oscar the potbellied pig, disappears. Lily will do anything to get him back--including battling the spirit of a powerful witch reaching out from the past. But even with the aid of her grandmother, unmasking a killer and saving Oscar might be more than one well-intentioned sorceress can handle."--
