"A clever puzzle, a hidden treasure, and a couple of kids you'll wish were your friends...Dive in!" - Sara Pennypacker, author of Pax

The letter waits in a book, in a box, in an attic, in an old house in Lambert, South Carolina. It's waiting for Candice Miller. When Candice finds the letter, she isn't sure she should read it. It's addressed to her grandmother, who left Lambert in shame. But the letter describes a young woman. An injustice that happened decades ago. A mystery enfolding the letter-writer. And the fortune that awaits the person who solves the puzzle. So with the help of Brandon Jones, the quiet boy across the street, she begins to decipher the clues. The challenge will lead them deep into Lambert's history, full of ugly deeds, forgotten heroes, and one great love; and deeper into their own families, with their own unspoken secrets. Can they find the fortune and fulfill the letter's promise before the answers slip into the past yet again?
