Colorado Territory, 1858
Descended from the mythical harpies, Petra Celaeno is content living a solitary life in the Colorado Territory until she meets dairy farmer, James Lloyd. As her relationship with James grows, Petra fights against her harpy instincts and questions the traditions of her ancestors.
James Lloyd came to Colorado looking for a fresh start, but he can not shake his obsession with a favorite myth from childhood. Something sinister is lurking beneath the earth of the Rockies and it is calling to James.
Life in the small town of Turning Creek is about to change. A terrible prophecy will be fulfilled and Petra will have to choose between protecting her home and saving the man she has come to love.
