"The Casual Vacancy," her first novel for adults, which published in September 2012, is No. 1 on the paperback fiction list.
"The Cuckoo's Calling," her first crime novel, originally published under the pseudonym Robert Galbraith, is No. 1 on the hardback fiction list.
"The Cuckoo's Calling" attracted little attention when it appeared in April as the work of an unknown, first-time novelist. But when word of Rowling's authorship was leaked to the media in mid-July, demand for the book spiked.
Earlier this week, Rowling accepted a settlement from the London law firm that disclosed her identity. The firm promised to make a donation to the Soldiers' Charity, an organization that supports British soldiers and their families. Rowling said she will also donate her royalties from the novel to the Soldiers' Charity for three years.
In a statement on the organization's website, Rowling said, "I always intended to give The Soldiers' Charity a donation out of Robert's royalties but I had not anticipated him making the bestseller list a mere three months after publication (indeed, I had not counted on him ever being there!)"
"The Cuckoo's Calling" isn't the only "Cuckoo" title on The Post's lists this week. Cliff Stoll's nonfiction story, "The Cuckoo's Egg: Tracking a Spy Through the Maze of Computer Espionage," is No. 4 on the nonfiction paperback list.
Why would a book from 1989 pop up now? Are NSA employees buying copies in bulk? Are Rowling fans confused about her pseudonym? Or is it just wizardry?
