Dogs in the Dead of Night

Beware of avalanches!

Jack and Annie have a new mission. They must find a rare flower to save one of their best friends! So when the magic tree house whisks them back in time to the Swiss Alps, they're confused. How can they find a flower buried under ice and snow? Jack thinks their mission is hopeless!

When they find an ancient monastery where monks and St. Bernards live, Annie gets them into more trouble. She offers to train a young dog named Barry. Then Barry runs away from the monastery, and Jack and Annie have a new task—find Barry!

Will Barry lead Jack and Annie to the mysterious flower? Or into danger? Before the night is over, Jack and Annie will be forced to use some crazy magic!
