Book excerpt: Hailey Walker's predictable life of school, track and home is about to be turned upside down when her father accepts a job that sends the whole family south for the summer. Along with her best friend, Alison, and the rest of the Walker family, Hailey heads to North Carolina for a summer full of horseback riding, swimming, and, oh, yes, solving the Mystery of the Freedom Trail. While helping at a church yard sale, Hailey finds a notebook that was written by a dead man. It contains riddles that promise to lead to treasure. Will Hailey and her friends be able to decode the clues and find the treasure? Where is the Freedom trail? What secrets and dangers does it hold? The story, as well as the trail, has many twists and turns. They not only find adventure, but also learn that there is more to the mystery than just a treasure-much more.
