How Many Books Has J.K. Rowling Written?
Joanne (J.K.) Rowling has written and subsequently published the seven books in the "Harry Potter" series, two novels for adults (one under the pseudonym Robert Galbraith), supplements to the Potter series, and a prequel to the Harry Potter series. Rowling works as a ghost writer, as well.
J.K. Rowling achieved her considerable fame and wealth as the author of the "Harry Potter" novels, but has since tried her hand at novels for older readers. "The Casual Vacancy" was published in 2012 and marked her first novel after the wildly popular fantasy fiction series wrapped up in 2007. Its content featured adult themes such as political scandal and drug use. Rowling went on to write "The Cuckoo's Calling," a detective novel, under the pseudonym Robert Galbraith. The book received positive reviews, but only became a bestseller when Rowling's identity as the real author was leaked to the press. It is the first in a planned trilogy, of which the second installment will be titled "The Silkworm."
