A Certain Slant of Light by Laura Whitcomb

From Goodreads:

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.

I think Katy possibly has excellent taste in hopelessly charming novels. First with Sorcery & Cecilia and now with A Certain Slant of Light, which she has recommended several times on her book blog as one of her all time favorites. It's not one that I think I would have picked up otherwise, but the strength of her recommendation was enough and holy cow I loved every second of it.

I felt like the book had all the wonderful heartfelt adolescent first love stuff that Sarah Dessen does so well but with the added bonus of gorgeous writing, an interesting supernatural element, and a wonderful bit of redemption at the end that had me sobbing as quietly as possible on my side of the bed so as not to wake Aaron since I stayed up way past bed time to finish reading.

An easy addition to my list of favorites.
