Books like Frozen Footprints

"Thou shalt not be afraid of the terror of the night." Eighteen-year-old twins Charlene and Max Perigard have grown up under the wealthy but tyrannical rule of their oil-tycoon grandfather. When Max disappears and a ransom note shows up, Charlene's world is shattered. She desperately tries to persuade her tight-fisted grandfather to pay, but the old man is convinced that Max is merely faking his kidnapping to extort money. Fearing the worst, Charlene determines to find her brother before it's too late. Her quest hurls her into a twisted, frigid world of snow and ice that leads to terror in an isolated cabin. Together the twins struggle for survival while enduring fierce trials of mind, body, and spirit. Devoid of all worldly comfort and consolation, will faith and hope be enough to get them through this chilling nightmare?
