Doesn't JK Rowling have enough money?
What's the big deal if this weepy guy wants to publish a reference book? His website was made out an earnest love for the books it seems.
I love those books, but sheesh are they confusing! I think there's enough harry potter money for them to share. Golden Compass has reference books, and you don't see Pullman throwing a fit. JK, you should just chill out and let your billions of dollars comfort you.
