Drawn to a Montana homestead and to a strange childhood companion she'd long forgotten, Joanna Chase and others converge on this remote ranch where a madman lurks with a vision to save the future through murder, forcing them all to come together to save themselves--and humanity.

As a girl, Joanna Chase thrived on Rustling Willows Ranch
in Montana until tragedy upended her life. Now thirty-four
and living in Santa Fe with only misty memories of the
past, she begins to receive pleas — by phone, through her
TV, in her dreams:
I am in a dark place, Jojo. Please come
and help me.
Heeding the disturbing appeals, Joanna
is compelled to return to Montana, and to a strange
childhood companion she had long forgotten.
She isn’t the only one drawn to the Montana farmstead.
People from all walks of life have converged at the
remote ranch. They are haunted, on the run, obsessed,
and seeking answers to the same omniscient danger
Joanna came to confront. All the while, on the outskirts of
Rustling Willows, a madman lurks with a vision to save the
future. Mass murder is the only way to see his frightening
manifesto come to pass.
Through a bizarre twist of seemingly coincidental
circumstances, a band of strangers now find themselves
under Montana’s big dark sky. Their lives entwined, they
face an encroaching horror. Unless they can defeat this
threat, it will spell the end for humanity
