MISSING. That's what the posters say about the girl. After bumping into a strange man at Yellowstone National Park who's secretly removing the posters, Calvin Crane thinks their van is being tailed. In a cramped van full of farts and Frito-feet with his whiny older sisters, parents and crabby Grandma Edith, Calvin can't shake that eerie feeling that he's being followed — suspicious-looking people, stange vehicles. Where is that little girl? Is he being stalked by a kidnapper? Does danger lurk just a couple of steps behind? As he learns more details about the missing girl, Calvin must face a search of his own. Sometimes being lost is more than just a matter of location.
