Want a fun supernatural literary mash-up? Then try My Plain Jane.
It's sort of the story of Jane Eyre...but mostly not. Charlotte Bronte herself is a character (my favorite one, I think). It's fun to watch her weave reality into fiction and vice versa.
Plus...ghosts!
I enjoyed most of the twists on the well-known characters, both literary and real.
Sadly...I wasn't a huge fan of Jane's character revision. I've read the real Jane Eyre two or three times and seen most of the movie versions more than once. I feel almost like Jane's my friend. I like her and respect her. But in My Plain Jane she seemed rather passive and boy-crazy and sometimes almost stupid. But...that's just my view of it.
These same authors (its three of them, and how they managed such a cohesive novel is really quite impressive) also wrote My Lady Jane about Lady Jane Grey. That book sparkled with humor. I was really impressed by how it never started taking itself too seriously, which is what most humorous fantasy/paranormal/historical fantasy books end up doing. My Plain Jane didn't quite match this standard, but it was still funny and a pleasant, light read.
I recommend them both.
And the actual Jane Eyre:
