Morrow Miller has a problem--well, more than one problem. First, it's his silly name, and, of course, his annoying sister . . .and then there is the space alien. Yes, a space alien who believes Morrow, a 10-year old boy, has been named by the President of the United States to help space aliens. It was all just a joke, but the alien isn't laughing and he wants Morrow to help him solve a riddle. Being visited by the alien was bad, having to solve the riddle was worse, dealing with the alien's gigantic, gassy, insect body made it horrible and trying to find a solution before the Silent Warriors arrive to destroy them all, made this Morrow's worst day ever
