A Certain Slant of Light and the follow-up novel, Under the Light.
than a hundred years, Helen has been a ghost with no way to communicate
with the living. She can see people, but they can't see her -- until
one day when someone looks right at her. James is a teenager, alive and
well, and he wants to get to know her. The more they talk, the more is
revealed about Helen's past, as she struggles to remember her life. How
did she die? Why can James see her? Light
reveals shades of darkness and traces of hope as Helen
struggles to recall her life -- and James begins to make her a part of his life.
I strongly recommend reading A Certain Slant of Light first. Though I suppose you could read Under the Light on
its own, trust me, if you know the characters went through in the first
book, it will make the second book all the more poignant.
Trivia time: The title of the novel comes from an Emily Dickinson poem.
