Suppose 'Harry Potter and the Sorcerer's Stone' is the first book in the Harry Potter series written by J.K. Rowling. It was originally published in the United Kingdom on June 26, 1997, and later in the United States as 'Harry Potter and the Philosopher's Stone'. The book follows the journey of a young wizard named Harry Potter as he discovers his magical abilities and uncovers the truth about his past.
Can we infer that 'Harry Potter and the Sorcerer's Stone' was the first book J.K. Rowling ever published?
