When Susan McAllister and her family returned to Beacon Hill, Susan found a lot more in the air than just happy childhood memories. A recent drug death at Baldwin Prep School had her best friend, Colleen, obsessively preoccupied. Colleen was sure that something unnatural had happened. And she seemed troubled - and afraid.

At first Susan didn't understand her friend's behavior. Perhaps Colleen was just upset about senior year, or her debut. Then Susan found Colleen dead. Of a drug overdose.

The police found drugs in Colleen's locker. Everyone said she'd been acting weird. Even Susan's boyfriend Patrick was convinced it was an accident. But Susan knew Colleen had never taken drugs. She knew something was very wrong. Something like murder. BkCvr
