The book "The Mysterious Manuscript of Nostradamus" by Geronimo Stilton

Far, far away, in a place surrounded by the deep waters of the Southern Rat Ocean, there is an unusual island inhabited exclusively by rodents. This is Mouse Island. Here lives Geronimo Stilton with his family and friends, who often drag him into unimaginable, but always extremely funny adventures... like the one you are about to read about. In his second book, Geronimo Stilton has decided to publish the manuscript of the mysterious rodent Nostradamus. When Sally Rasmussen steals the manuscript, new adventures for Stilton begin.
