Philip-Jon Haarsma , more commonly known as PJ Haarsma, is a Canadian born science fiction author best known for his creation of the Rings of Orbis universe, which encompasses The Softwire series of books. Haarsma created a free, online role-playing game, also called the Rings of Orbis, set in the same universe. Both the book-series and the game target young, often reluctant readers in an attempt to encourage them by rewarding them for reading.
