The White Devil, by Justin Evans
The Harrow School is home to privileged adolescents known as much for their distinctive dress and traditions as for their arrogance and schoolboy cruelty. Seventeen-year-old American Andrew Taylor is enrolled in the esteemed British institution by his father, who hopes that the school's discipline will put some distance between his son and his troubled past in the States.
But trouble—and danger—seem to follow Andrew. When one of his schoolmates and friends dies mysteriously of a severe pulmonary illness, Andrew is blamed and is soon an outcast, spurned by nearly all his peers. And there is the pale, strange boy who begins to visit him at night. Either Andrew is losing his mind, or the house legend about his dormitory being haunted is true."
I couldn't put this one down, it was really good. But it was also a very strange read!
