This just in: Dave Eggers is publishing a new novel in October 2013. Called The Circle (Knopf. 504p. ISBN 97803853513939780. $27.95), it’s particularly relevant to our current concerns about Internet-facilitated invasion of privacy. Heroine Mae Holland is thrilled to be hired by the Circle, the world’s most powerful Internet company, which melds users’ personal emails, social media, banking, and purchasing into one grand online identity through a universal operating system. Of course, that means the company knows and evaluates every move each user makes. Mae is mightily impressed by the glass towers, all-night parties, and rock stars performing on the lawn, but her idealism is soon corroded, and the novel spirals into suspense as Mae tries to understand what’s really happening. In fact, this is billed as Eggers’s most commercial title yet.
