While he gave his manuscript to his agent and editor to review, Riordan took his book to a group of middle schoolers to critique. With their help, he came up with the name of the book and invented Percy's magic sword. Riordan first sent out the manuscript for "The Lightning Thief" under a pseudonym, as he did not want to rely on anyone in the publisher industry, who would have known him through his previous work. After many rejections, an agent picked up the manuscript as she liked its premise. In 2004 the book was sold to Miramax Books for enough money that Riordan could quit his job to focus on writing. The book has since been released in multiple versions (including hardcover, paperback, and audio editions) and has been translated and published all over the world.
