"The Aldens are at Wildcat Crossing, a recreated frontier town full of cowboy fun. But when horses disappear and other pranks threaten to ruin the Wild West show, the Boxcar Children must find out who's the varmint causing all the trouble"--

Because they do not want to be separated, four orphaned children run away and live in an old abandoned boxcar

The Alden children, snowbound in a vacation cabin, discover adventure in surrounding wild life, three children they find in the snow, and a search for a lost recipe.
