Hoofprints in the snow

Lyssa Hynde knows the Wyoming winters are cold, lonely, and dangerous. But she wouldn't give them up for anything. There's nothing she likes better than to gallop her three-day event horse, Blue, through knee-high fresh powder. One day when she's out for her morning ride, Lyssa follows a trail of mysterious hoofprints that takes her high into the mountains. Climbing a snowdrift, she and Blue set off an avalanche that builds in forces as it heads straight for her ranch. Will Lyssa make it home in time to warn her family and save the other animals? Will she find the mystery horse that led her astray in the first place?
