Arcadia is the second novel by Lauren Groff, published in 2012 by Hachette. It is set in Upstate New York during the 1960s and 70s, and depicts a utopian commune through the eyes of the settlement's first-born child, Bit. The commune is situated on the grounds of an old and crumbling homestead. The book then splits storylines to depict a post-apocalyptic future ravaged by global warming. The novel received high praise from The New York Times, The Kenyon Review, NPR, and Guernica.
