Book excerpt: Colds travel from person to person, so one little boy imagines all the places his cold might visit after it leaves him. This little cold germ rides the school bus, climbs mountains, sails across the ocean, and visits every continent before it reaches its final destination- right across the hall in his sister's room. Nora Krug's bright, bold artwork makes for a very colorful travelogue, and Molly Rausch's funny story of a global expedition also celebrates imaginative thinking.
