Danger on Panther Peak

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?
