Shadows of Caesar's Creek — Sharon M. Draper

In the third of the Clubhouse Mysteries series, Ziggy and his friends are excited about their overnight camping trip to Caesar's Creek State Park. The park is named after a Shawnee chief and their camp counselor is a descendant of Caesar! She fills the campers' imaginations with fun (and spooky!) stories about her ancestors and the Shawnee legends. But when Ziggy and the rest of the Clubhouse gang decide to test their courage like the Shawnee youth did, it doesn't go quite as planned. And when they end up lost, strange things start to happen. Are the creepy sounds simply animals roaming the woods? Or are the ancient spirits of Caesar back to haunt their old stomping grounds?
