The Maharal's Code: A Yoni Stern Adventure (The Shomrim Series)

Three weeks after his bar mitzvah, Yoni Stern receives a mission he never asked for.

His grandfather — a man who spent his life working quietly in the shadows — has left him a document, a compass, and a set of instructions. Somewhere in the Old Jewish Cemetery in Prague, beneath a gravestone that has stood for decades, lies a sealed case containing secrets that powerful people have been searching for since the end of the Second World War. Yoni's job is simple: find it, retrieve it, and get it out of the city without being noticed.

He is thirteen years old. He is on a school trip. And he is being watched.

The Maharal's Code is a gripping adventure rooted in real history — the story of one boy's first mission, a wartime secret that never quite ended, and the question of what we owe to the past.
