When a blindingly bright meteor strikes the Plateau, Challenger, Roxton, and Marguerite set out to investigate the impact site. But the closer they get, the colder the temperature becomes. As the explorers turn back, they discover what appears to be a victim of the intense cold - a beautiful, blue-skinned woman, unconscious and nearly frozen . To save her life, the explorers take her back with them. When the frigid temperatures reach the Treehouse and all attempts to warm the woman makes her condition worse, Challenger suspects that things are not as they appear . Roxton and Marguerite are attacked by a group of blue-skinned male warriors and the truth becomes clear - the heat-absorbing meteorite now buried in the Plateau is the first step in a terrifying invasion of creatures who need the cold to survive.
