This book was published in 1946 and was later made into a movie starring Olivia deHaviland. It is fiction, but... it is interesting to note that conditions in state hospitals haven't changed much in 60 years. If you are interested in mental health issues, this should be part of your library. It never names her disease, but it's clear it's schizophrenia and it's an interesting look from a patient's perspective. Makes me wonder about the author. Anyway...highly recommended.
