I am always reading more than one book at a time, so...
Jane Eyre, reading this all the time.
The Secret Diary's of Charlotte Bronte by Syrie James.
The Crimson Petal and The White by Michel Faber.
Dracula by Bram Stoker.
Do actually read them all within the same time frame or do you pick one, stick with it for a week, then move on to another? Also, I think the BBC made a miniseries for The Crimson Petal and The White recently. I've been thinking about watching it. You'll have to let me know how it is.
