In June 1994, Riordan finished the story. He started looking for agents to publish it. He went to many local colleges to find an editor before finding an agent. He gave his manuscript to his agent and editor to review. At the same time, he gave the book to some sixth, seventh and eighth graders to read and tell him what was good or bad about it. They named the book and helped Riordan describe how Percy's sword (Riptide) worked. In June 1997, Riordan signed with Bantam Books to prepare the book for publishing. In 2004, Miramax Books bought the book. The money was enough for Riordan to quit his teaching job and spend his time on writing. The book was published on June 28, 2005. It sold over 1.2 million copies. The book had hardcover, softcover and audio editions. It has been translated into many languages. It has been published all over the world.
