Rowling, follows the adventures of a young wizard named Harry Potter and his friends Hermione Granger and Ron Weasley as they attend Hogwarts School of Witchcraft and Wizardry. The series has become one of the best-selling book series in history, with millions of copies sold worldwide.
Can we infer that "J.K. Rowling only wrote one book in the Harry Potter series"?
