In the third installment of the Angus Books Series, Angus and the Forgotten Trails , 11-year-old Angus McBride and his friends are trapped in an abandoned mine that is likely filled with undiscovered gold and silver lodes. This captivating tale features three elementary school friends who experience a taste of the Old West in Wickenburg, Arizona, during an amazing seven days at the Crazy Horse Dude Ranch. During their stay, the kids stay busy hiking, fishing, swimming, horseback riding, and roping cattle. But it's during a visit to the ghost town of Vulture City--home of the legendary Vulture Gold Mine--that Angus and his friends, Andrew and Taylor, find trouble. When Angus is injured after falling into a secret entrance of the abandoned mine, Andrew and Taylor attempt to rescue him, but all of them get lost in the process. With little food and water and many miles of dark and creepy tunnels, hundreds of feet underground, the three friends face the most dangerous and frightening adventure of their lives. Is all the treasure that is hidden in the forgotten walls of the Vulture Mine worth risking their lives?
