The Thea Stilton Special Edition series features the Thea Sisters, a group of five mouse friends from Mouseford Academy, on longer fantasy adventures. Published under the Geronimo Stilton brand, these books are a spin-off centered on Thea Stilton and her friends rather than Geronimo himself. The first Special Edition, The Journey to Atlantis, came out in 2009.
Across nine books, the Thea Sisters travel to magical places like underwater kingdoms, cloud castles, flower-covered lands, and fairy realms. The Special Editions are longer than the standard Thea Stilton chapter books and include colorful illustrations throughout. They are aimed at young readers who enjoy fantasy settings with friendship and teamwork at the center of each story.
