Annihilation

Area X has been cut off from the rest of the continent for decades. Nature has reclaimed the last vestiges of human civilization. The first expedition returned with reports of a pristine, Edenic landscape; all the members of the second expedition committed suicide; the third expedition died in a hail of gunfire as its members turned on one another; the members of the eleventh expedition returned as shadows of their former selves, and within months of their return, all had died of aggressive cancer. This is the twelfth expedition. Their group is made up of four women: an anthropologist, a surveyor, a psychologist, and a biologist.
