Cannot get the right answer to the Challenge Task

Challenge Task 2 of 2 In the library database, how many books are by the author of "J.K. Rowling"?

Alias the result as jk_book_count.

The books table has the columns id, title, author, genre and first_published.

Even though I did it this way, the message "Bummer! Your query didn't perform the correct count." still showed up. Cannot figured out the correct answer. Please help!

SELECT COUNT(author) AS jk_book_count FROM books WHERE author = "J.K.Rowling";
