The Belonging Kind is a very special sort of science-fiction: one that traverses genres and yet remains firmly rooted in contemporary setting and concerns. Far more than just body horror and paranoia, The Belonging Kind is a comment on the alienation and isolation inherent to modern society. Gibson's protagonist seems somewhat of a homage to Kafka's Gregor Samsa in Die Verwandlung, but in reverse. Rather than being the everyman who suddenly realizes his alienation and is thus transformed, Gibson's Coretti begins outside the system and ends by merging with it. What we're left with is a horror at what that system is—a place where individuals carry no real meaning or life, they simply move from one room to the next, parroting the conversation of the moment, and killing time. These are unthinking, unfeeling, shape-shifting shells. The assimilated proletariat.
Needless to say, this is an expertly-crafted, thought-provoking piece that I can't recommend highly enough.
