Ghost Boy — Jean Simon

Once, in a small town paralyzed with fear, a sadistic human monster moved undetected, leaving a terrifying trail of bloody death...and few clues. That was twenty-five years ago. Today, two more children have just been found brutally murdered.

Eleven-year-old Joely calls this town her new home. She calls the shy, strange boy named Martin her new friend. But Martin has a secret: He knows who the killer is. Because he was the first victim. And unless he can stop the killings, Joely's going to be the next one.

In this town, every child has a reason to be afraid.
