Stay off Panther Peak. When Tom and his family move to his grandfather"s ranch, Grandpa warns Tom to stay away from Panther Peak, even though there hasn"t been a panther in the area for decades. But when Tom sees a large, black creature in the mountains near their ranch, and something starts killing off their livestock, he has to wonder -- could Grandpa"s tales about panthers be true? One winter morning Tom sees a dark shape move silently through the fog, spooking the animals in the barn. Later that day Tom and his grandfather are home alone when a blizzard hits and Grandpa is injured in an accident. With the phone lines dead, Tom must take his horse and ride for help -- by himself -- through the panther"s territory. Can he reach safety in time to save his grandfather before the panther strikes again?
