Geronimo Stilton: 25 Years of happiness
2025 is a truly special year—no, a Squeaktastic one! This year, our publishing house, Piemme, is celebrating 25 years of incredible success with none other than Geronimo Stilton.
Created by Elisabetta Dami, the beloved mouse journalist has become a global phenomenon, capturing the hearts of millions of young readers with his funny, clever, and exciting adventures. An Italian success story, Geronimo Stilton has been translated into 52 languages and has sold over 187 million copies worldwide! In Italy alone, a Geronimo Stilton book is sold every minute!
But What’s His Secret? Without a doubt, Geronimo Stilton’s magic lies in his universal language, one that speaks to fundamental values like friendship, empathy, kindness, respect for others and the world around us, and loyalty. But that’s not all! His adventures take readers across time and space, from ancient worlds to realms of pure imagination, always alongside a group of unforgettable characters from his hometown of New Mouse City. Over the years, young readers have grown to love and cherish them, including his sister Thea (also the author of many bestselling books, most of which star the beloved Thea Sisters), his cousin Trap, his nephew Benjamin, and his niece Trappy. And let’s not forget his friends, like Ficcanaso Squitt, Rebella Strong and Ficcagenio Squitt! Surrounding Geronimo is a true community of friends and family.
“For 25 years, we’ve shared the same passion, the same excitement, and the same joy in bringing the love of reading and imagination to our young readers,” says Elisabetta Dami. “Kids see me as the ‘Mum of Geronimo Stilton’—and even today, that touches my heart just as much as it did the first time. I see it as a sign of deep affection and trust, which inspires me to keep going with the same love… for the next 25 years!”. “But what’s our secret? Caring deeply about our young readers, listening to them, and sharing fundamental, universal values, helping guide them as they grow, in Italy and around the world,” Dami concludes.
Geronimo Stilton and his friends have explored countless topics in their adventures, but one is particularly close to his heart—because it’s more than just a theme; it’s a fundamental right that everyone should strive to protect, especially for children: happiness.
To celebrate this milestone anniversary, the famous mouse journalist has decided to make happiness the central theme of all activities in 2025. With the support of bookstores, fairs, festivals, schools, and many dedicated local partners, Geronimo will spread his message of happiness across Italy, from south to north, through a series of special events that explore this precious theme in all its many forms. Children will have the chance to meet Geronimo Stilton in person—fur and whiskers included—hear him tell his adventures firsthand and even shake his paw! And thanks to the new initiative “Tell Geronimo!”, young readers will become the true stars of these events. Geronimo’s goal is to collect thoughts of happiness, hopes, and the little (and big) joys of everyday life from all the kids who take part. If they wish, they can leave a message, a note, or even a letter—”Tell Geronimo!” will be a way to listen and share, two values that brighten Stilton’s world.
Starting in Messina, on the 19th of February Geronimo will meet with five local schools, the famous mouse journalist will set off on a happiness-filled journey across Italy. His squeaktastic tour will take him to Rome and Lazio, Calabria, Puglia, Tuscany, and Piedmont—just to name a few stops—where he will meet thousands of children and share songs, reflections, important messages, readings, emotions, and fascinating insights related to his books and those of his sister, Thea Stilton.
This year, once again, Geronimo Stilton and Thea Stilton will stand out in the Italian (and international) publishing scene with fun and captivating stories that are not only entertaining but also full of educational value—guiding young readers on a journey of discovery, both through the world around them and through exciting imaginary realms.
Some of the most exciting new releases in the first half of the year include My Day with Lucy (in bookstores on February 25th), a time-traveling adventure with Geronimo alongside the Australopithecus Lucy; Captain Lupita, a brand-new series by Thea Stilton featuring an all-female pirate adventure; Time Travel: Great Inventions, a journey through history to discover the inventions that have improved humanity’s way of life; and a special book dedicated entirely to the theme of Happiness, coming in May.
And finally, one last surprise: to celebrate this milestone anniversary, Geronimo Stilton will have a brand-new, special logo accompanying him
