Nightborn: Coldfire Rising - C. S. Friedman - Bog

"A ship full of colonists arrive on a seemingly hospitable planet, only to discover that it harbors a terrifying secret. Soon the settlers find themselves caught up in a desperate battle for survival against the fae, a natural force with the power to prey upon the human mind itself, bringing a person's greatest fears and darkest nightmares to life. As Colony Commander Leon Case and Chief Medic Lise Perez struggle to find a way to control the fae before more people die, other settlers have ideas of their own...and they may prove more of a threat to colony than the fae itself. This is a tale that blends sci-fi, fantasy, and horror, suspenseful and emotionally intense, as a handful of humans struggle to survive on an alien world that seems determined to kill them. In the end they will have to draw upon both scientific knowledge and mystical traditions to save themselves."--Publisher marketing.
