A Certain Slant of Light by Laura Whitcomb
Someone was looking at me, a disturbing sensation if you're dead. Though I could not feel paper between my fingers, smell ink, or taste the tip of a pencil, I could see and hear the world with all the clarity of the Living. They, on the other hand, did not see me as a shadow or a floating vapor. To the Quick, I was empty air. Or so I thought.
In the class of the high school English teacher she has been haunting, Helen feels them: For the first time in 130 years, human eyes are looking at her. They belong to a boy, a boy who has not seemed remarkable until now. And Helen–terrified, but intrigued–is drawn to him. The fact that he is in a body and she is not presents this unlikely couple with their first challenge. But as the lovers struggle to find a way to be together, they begin to discover the secrets of their former lives and of the young people they come to possess.
