内容简介：
Treasure. A mysterious death. A dark crypt. All these await 12-year-old Andrew Baker as he travels to Slovenia, the land his grandmother fled many decades earlier. Grandma makes him promise to return with a treasure she left behind. Exactly what the treasure might be is unclear, and Andrewas mom is certain it is a figment of her elderly motheras imagination. But Andrew is convinced Grandma would not lie to him and makes finding the treasure his mission. In the process, he uncovers a dark family past and political intrigue dating back to World War II. His search takes him to the shores of Sloveniaas beautiful Lake Bled, its capital city, Ljubljana, and into a forbidding prison.
