The lost cipher

"Lucas's father has recently died in Afghanistan, and to help him cope, his grandmother sends him to Camp Kawani, a camp for kids who have lost a parent. While there, he hears about the local legend of Thomas Jefferson Beale. Beale supposedly hid a hoard of gold in the mountains 200 years before. The location is encrypted in a set of codes no one has ever been able to decipher. When Lucas and his newfound friends decide to track down the treasure, they embark on a mission that could be too dangerous to survive."--Provided by publisher.
