So the authors I have read the most from.
1. Shakespeare - I read the complete works; it's less impressive when I point out I am an English degree holder.
2. Terry Pratchett - all of the current Discworld, his Johnny Books, various other works. I haven't read the Science of Discworld 4 yet.
3. Peter Ackroyd- roughly 24 of his books.
4. A.S.Byatt - her works. I'm not missing anything there.
5.Isak Dinesan - including her essays
6. Ruth Rendell and P.D.James - not all of each. Yet.
7. Angela Carter - all her works.
8. Jim C. Hines
9. Margret Atwood
10. Chelsea Quinn Yarbro - her Count St. Germain series and various other works.
11. Joanne Harris
