The Mystery Tunnel

Small, dull, Kirksbourgh, Ohio, is the last place on earth 13-year-old Emily Parker wanted to live. She couldn't understand why her father would trade an exciting archeology career that took them around the world for a stuffy classroom. Emily soon discovers danger and adventure aren't limited to archeology digs when she and her friends find a secret underground tunnel-a part of Kirksbourgh's forgotten past. The tunnel is part of the Underground Railroad and leads them to secret rooms, trap doors, and a plot to harm their friend Mac for his land. As the danger to Mac increases, can the three devise a daring plan using the tunnel to protect their friend from his enemies and save his land?
