Somewhere… in the mountains of Colorado is a group of eco-vigilantes led by a single-minded woman. She wants to “return the Colorado River to its natural, free-flowing state.”
Someone… Mikel Mas, water lawyer and outdoorsman, experiences unexplained, odd occurrences and encounters. Trying to make sense of it all, he inadvertently learns of the group and its leader. At the same time, the leaders of the vigilantes become aware of Mikel and his inquisitive efforts.
