I don't repeat a lot of authors, but surprisingly there are 10 where I've read at least 5 of their books:
Stephen King (by a mile)
Neil Gaiman
John Grisham
Joe Hill
JK Rowling
George R.R. Martin
James Michener
Malcolm Gladwell
Nathaniel Philbrick
Michael Crichton
This list was a bit of an eye-opener for me. With the exception of Rowling (I read the Harry Potter b4 we knew she was awful), everyone on the list is male and of them, only Gladwell is not white.
