I'm pleased to announce that an original Percy Jackson story, "The Sword of Hades," will be published for World Book Day in the UK next spring, back-to-back with Terry Deary's Horrible Histories: Groovy Greeks. The goal of World Book Day is youth literacy, and specially selected double titles are made available to British schoolchildren for £1 tokens. The idea is to get more high-interest books into the hands of more young readers. The Percy story is not a novel, but is quite long, over fifty pages, and takes place between The Battle of the Labyrinth and Percy Jackson book 5. For the time being, the story will be published exclusively in the UK -- sorry, everyone else! -- although you may see "Sword of Hades" published in a different format in the U.S. some time in the future. More information about that as it becomes available.
