Country of the Wolf — Sharon Wagner

The Charm
seemed beautiful from a distance, but when Colleen Forester held the figure of a dog closer, the beauty disappeared; the friendly animal became a snarling wolf whose ruby eyes seemed a mark of insanity. She shivered, and then Jackie found the note. "Stay away from Lobo Lodge!"

The girls decided it must be a prank; they were looking forward to Christmas at the Montana ski resort after a hectic season of teaching in Arizona. The lodge was owned by Jackie's aunt...but when they arrived, they found that other forces were in power, dark forces, forces that fitted the evil hints of the silver charm. For Lobo Lodge was well-named, and this was indeed the country of the wolf--a wolf who could appear in human guise! The wolf was absolute master in his country; his command was law--and his law demanded the worship of evil! Were Colleen and Jackie fated to become victim to the Curse of the Wolf?
