Jack and Annie travel to a monastery in the Swiss Alps where, with the help of St. Bernard dogs and magic, they seek the second of four special objects necessary to break the spell on the wizard Merlin's beloved penguin, Penny.
Eleven-year-old Charlotte is not a dog person but does not like that the rest of her family neglects their Saint Bernard puppy, and so with a lot of determination and a little sneakiness, she works on finding a good home for the gentle giant.
