Horrible. Absolutely horrible. If the poor style doesn't make your brain bleed, the lack of any coherent story line will do so. There is much great literature out there, so don't waste your time on this.
I had read this book in high school and didn't like it. Reading it again now as an adult I found it much more enjoyable.
An interesting insight into the time (1860s) that this was written. The story is about a husband and wife whose marriage is tested by the husband's love for their child's governess.
