The School of Noble Mice

The thoughtful mouse Mus, the romantic Smussi, and the determined Fri are first-grade students at the School of Noble Mice. By chance, they discover a secret underground passage that leads to a castle and realize that someone wants to steal the treasures. They conduct an investigation and develop a plan to stop the wrongdoer and free the castle's prisoner.
"The School of Noble Mice" became a finalist in the "Best Youth Bestseller" competition and was also included in the longlist of "New Book".
