A Certain Slant of Light

Altho to be fair, she wrote it like a year before her death, and there's a big change from the first part, which is depressing but readable, to the second part which takes place after a big timeskip and tries to tell way too much history in too few pages. I always wonder if there was a big break in the writing of the book, or if she just pushed herself too hard trying to make sure she finished it.
