When does nature become unnatural? That is the question posed by author Jeff Vandermeer in Annihilation, the first installment of a proposed trilogy (entitled Southern Reach), all three parts to be published in 2014. In brief, the story involves a team of four (a biologist, an anthropologist, a psychologist, and a surveyor) who set out into an area known as Area X. The area is abandoned and cut off from the rest of civilization. They are the 12th expedition. The other expeditions have been fraught with disappearances, suicides, aggressive cancers, and mental trauma.
