"The post office is closed, and that means it's time for Mr. Postmouse and his family to take a vacation. Of course, he'll need to bring along a few parcels --- ?a postmouse's rounds are never done!? --- as he and Mrs. Mouse, Milo, Lulu and Pip set off on an around-the-world tour. Doing whatever it takes to reach their destinations (including traveling by hot-air balloon, cruise ship and camel!), the intrepid mouse family treks from the forest to the sea, the desert to the ice field, finding adventure, new discoveries and animal friends at every far-flung stop. And all along the way, Mr. Postmouse never misses a delivery!"-- Amazon.com.
