Who's There? (Beech Tree Chapter Books)

Can Drew solve the terrifying mystery behind the haunting of Rose Hill? Two orphans are taken in by family they never knew existed. The old mansion Drew and Evan's father grew up in quickly feels like home. But soon Drew senses a chilling ghostly presence. Dad never told Drew about the tragic events that drove him from home, and her aunt and grandfather are just as secretive. But if Drew can't discover why Rose Hill is haunted, her own life may be in jeopardy. When fourteen-year-old Drew and her mute younger brother come to live with their father's estranged relatives after their parents' sudden death, they discover that the house is haunted by ghosts and a deadly family secret.
