Thea Stilton and the Lost Letters

Reach for this book when your child is ready to transition from early readers to longer chapter books and needs a story that balances excitement with a sense of security. It is particularly helpful for kids who feel discouraged when things do not go right the first time, as it emphasizes the value of persistence during a difficult investigation. In this adventure, the Thea Sisters travel to Russia where a high-stakes robbery at a ballet school pulls them into a complex mystery.
