The Silver Sword by Ian Serraillier
The book is a poignant tale of resilience and hope set against the backdrop of World War II. It follows the Balicki children—Ruth, Edek, and Bronia—as they are separated from their parents in war-torn Poland. When they come across a paperknife in the shape of a silver sword, it becomes a symbol of their quest to reunite with their parents who are believed to be in Switzerland. Along their harrowing journey, they encounter a diverse group of fellow refugees and face numerous challenges, but their unwavering spirit and the friendships they forge help them to overcome adversity and keep their family's bond alive across the ravages of war.
