Salt and Pepper's first-place finish in the National Archaeologists Association essay competition earns them an awesome prize-a month-long trip to an archeological dig in New Mexico, the site of an ancient Anasazi cliff dwelling. In typical Salt-and-Pepper style, though, things get complicated awfully quickly. Before the teenaged duo even leave home (with Salt's mega-annoying little brother, Hal, in tow), they learn that one of the site's archeologists has mysteriously disappeared. And when they finally arrive on the scene, a strange-looking man seems to be following them. It's another mysterious adventure for Salt and Pepper, with a time-travel twist that's sure to have readers on the edge of their seats!
