Every year Stoneybrook Middle School (the whole school!) gets invited to Leicester Lodge in Vermont for a week of winter adventure!

This trip sure isn't like any other! A busload of little kids unexpectedly needs baby-sitters. Mary Anne uncovers a ghost in the lodge. Claudia and Stacey both fall in love with handsome French skiers. Kristy is helping her team win the Winter War . . . while California Dawn can barely stand up in her skates. And if it doesn't stop snowing, SMS may be snowbound until spring!
