After months of intensive training, Billy is finally ready to go on his first solo creatch op for AFMEC (Allied Forces for the Management of Extraterritorial Creatches). Godzilla-like monsters are menacing the Chinese mountain village of Hua Qing. Billy is more than fired up to fend them off - until he discovers that bossy Ana García will be tagging along. Though Ana is no older than Billy, she's a full-fledged AFMEC agent - and doesn't hesitate to remind him of that fact. Whenever possible. At first, the mission is pretty straightforward. Billy and Ana help Hua Qing fight off the monsters, and life for the villagers goes back to normal. But Billy can't shake the feeling that things in Hua Qing are not what they seem. Is Billy being paranoid? Or is something really bad about to go down? If Billy is right, then he, Ana, and the villagers of Hua Qing are in a whole lot of trouble.
