Eh.  It’s okay.  The main character is Rhina O’Virus, and it basically tells the story of how a germ invades a body to cause a cold.  The illustrations are bright and cheerful, but not exactly informative.  The story is told in terms of buildings and copy machines and police and parties, but in order to make the connections between the story and the reality of what happens, it’s important to read the straight-forward paragraph on the last page, which mostly kids won’t read. It’s kinda hard to follow.
