Aliens Eek and Ack want to find out why Earth is so hard to conquer. They dress up in “traditional Earthling costumes” and arrive on the planet during a meteor shower, a perfect disguise for their landing. They do not realize that it is Halloween or that the Wolfman is on the loose. Harpster’s characters are wonderfully drawn in dark colors, and readers see the full emotion behind these charming aliens.
