All Sheriff Jeb Hawkins and his wife Cassie want is a family. After three grueling miscarriages, their dream is finally coming true. Sadly, their joy is shadowed in the most vile way: two decapitated children have been found in their Mennonite prairie town, their heads nowhere in sight, gemstones with an odd symbol etched into the surface in their hands.

Caches of strange artifacts are popping up, the wind is relentless and now another child is missing.

Hundreds of miles away archeologist Eric Blair discovers a skeleton with a stone bearing the same insignia. Soon Eric is on his way to Kansas, drawn into a web spun by an inhuman killer stalking the prairie, a killer that wants Cassie.
