J. K. Rowling is a British author who is famous for writing the Harry Potter series. Rowling was working as a secretary for a human rights organization called Amnesty International when she thought of the idea for the Harry Potter books. She thought of the idea for the books while she sat on a delayed train from Manchester to London in 1990. Five years later she had finished the first book in the series called Harry Potter and the Philosopher’s Stone.
This book was first published in 1997 by a small publishing house called Bloomsbury. This company printed only 1000 copies, and 500 of them were sent to libraries. This won the British Book Award for the Children’s Book of the Year. The people who bought one of these original copies now have a very valuable book. These copies are now worth between $25,000 and $40,000. J. K. Rowling wrote six other Harry Potter books. The final one is called Harry Potter and the Deathly Hallows. This was published in 2007. These books have become popular all over the world. They have won many awards and sold hundreds of millions of copies.
