Ancient Enemy-by Mark Lukens

Ancient Enemy – it wants things . . . you have to give it what it wants.

Stella, an archaeologist specializing in Anasazi culture, and David, a mysterious Navajo boy, are on the run from something terrifying. As they flee up into the snowy mountains of Colorado, they are carjacked by criminals escaping a botched bank robbery. Caught in a blizzard, they must take refuge in what they believe is an abandoned cabin. It’s at this cabin where they will face horrors beyond their imagination.

Seven hundred years ago the Anasazi people built massive cities in what is now the southwestern United States . . . and then they vanished.
